Ling Yun didn't notice the movements of the two girls, he took the book handed over by Guo Yan and carefully read the title on it.

Fortunately, the knowledge of high school has not been forgotten, and some things are still understood, otherwise I don't know who tutors whom today.

After reading it for a few minutes, he pointed to the above question and explained, "This problem should be like this, you write the function directly according to the known conditions, which is a quadratic function." You should know how to express quadratic functions in geometric patterns! ”

Ling Yun said this, but he didn't see Guo Yan next to him make a sound.

He turned his head strangely, "What are you doing here?" ”

"Ahh Guo Yan turned his head and hurriedly said, "I'll look at it, Brother Lingyun, you continue to speak." ”

With a smile on his face, Ling Yun rolled his eyes slightly, casually drew a parabola on it, and then marked the coordinates, "You can find the range by using the parabola, it's very simple." ”

"I see." Guo Yan showed a look of sudden realization, "Brother Lingyun, you are really amazing, the teacher told me many times that I couldn't understand, and I completely understood after you only said it once." ”

"Alright, don't compliment me here, hurry up and finish writing." Ling Yun rolled his eyes slightly, then handed the book out.

"Brother Lingyun, I don't know this question." Tinsonson said with a sad face.

"Alright, I'll show you."

Ling Yun leaned towards Ding Sensen's side and casually took the book that Ding Sensen handed over, "Which problem?" ”

"This is it." Ding Sensen lay on Ling Yun's shoulder. He stretched out his finger, which was as white as a shallot, and tapped it on the paper.

Ling Yun glanced twice, "Okay, I'll take a look at that." ”

studied it carefully, and this time it was Ding Sensen looking at Guo Yan proudly, and he was still making a strange face to Guo Yan behind his back.

Guo Yan gritted his teeth with hatred this time, so he directly flipped through the book twice, and said to Ling Yun again, "Brother Ling Yun, this formula." This question is still this one. I don't really understand, can you tell me about it. ”

"Wait a minute, first think carefully about the solution I just told you, you must learn to draw inferences. That's how you can learn well. Ling Yun raised his head and said to Guo Yan. Then he lowered his head and studied Tensonson's book carefully.

I watched it for a while. Ling Yun finally figured it out, and stretched out his hand to explain. "This problem is not difficult, you only need to express all the unknowns in X, and you can get a function, and it is easy to solve the problem through the function guò."

Ding Sensen lay next to Ling Yun, sniffing the smell of his body, and his pretty face was slightly rosy. "Is that so? But I still don't know much about how this function is listed. ”

"So, you look at this, you list all the known conditions, and you can relate these known conditions to the results, very simply, so that you can."

Ling Yun wrote, then handed the book to Ding Sensen.

"I see!" Ding Sensen nodded, "Brother Lingyun is still powerful with you." ”

"Okay, don't boast here, I'll go show Guo Yan."

Ling Yun directly took Guo Yan's book, and then explained for a while, and Ding Sensen over there shouted again.

If it was repeated, Ling Yun also felt that something was wrong.

When it was finally time for Guo Yan, Ling Yun glanced at the above topic, raised his eyebrows slightly, and finally reacted, what was the situation.

"You asked me this question just now, why are you asking it again now?" Ling Yun glanced at Guo Yan slightly, and then asked strangely.

"Did I ask? Oops, I read it wrong. Guo Yan hurriedly took the book back and turned two more pages, "It's this, it's this." ”

Guo Yan hurriedly pointed forward, Ling Yun rolled his eyes slightly, "I also told you about this just now." ”

"I've talked about this too?" Guo Yan opened his mouth wide and turned two more pages, "This, it must be this." ”

Ding Sensen looked at Guo Yan's hurried appearance, and his expression was about to bloom.

Ling Yun took Guo Yan's book, but he didn't turn it over, but glanced at the two girls next to him, "Okay, don't pretend here, just now I saw that something was wrong with the two of you, and it seems that you have to find a way." ”

"Brother Lingyun, you have to believe me, what I said is the truth, I really made a mistake just now, and I will definitely not be wrong this time." As she spoke, her beautiful eyes widened.

"Okay, I can see clearly what kind of medicine you two are selling in the gourd."

Ling Yun directly opened the book, and then said, "Let's start reviewing the first chapter today." ”

"Ah, do you want to start with the first chapter?" The two girls had bitter faces, but as they spoke, they both came to Ling Yun's side.

"You two sit across from me and finish everything I need to learn."

The expressions of the two girls were suddenly unnatural.

Unexpectedly, these two girls are really in trouble.

Ling Yun couldn't help but stand up, "Since you two don't want to get up, then how can I wake up when I get up!" ”

Saying that, Ling Yun walked out directly from the side, came to the opposite side, and sat down.

"Alright, let's start with the first chapter, and I'll list all the knowledge points for you. Tomorrow bring all the workbooks and you do the questions, and then I'll help you solve them. ”

"You two read one, I'll read one."

Both girls' eyes widened and they looked innocent.

"I'm a girl who likes to study hard, and I'm not interested in the kind of people who play around all day." Ling Yun had already seen the thoughts of the two little girls, so he talked nonsense here.

The two girls' eyes widened at the same time when they heard Ling Yun say this.

"Brother Lingyun, don't worry, I will definitely study hard." Guo Yan immediately began to express his attitude.

Tinson, who was next to him, also exclaimed, "Me too." ”

"That's good." Ling Yun nodded slightly, and threw out another benefit, "Didn't you say that there is a bungee jumping place over there, if you have almost learned, I can take you to bungee jumping, if someone doesn't study well, then don't take her." ”

Hearing Ling Yun say this, the two girls' eyes widened even more.

"Brother Lingyun, you must take me, I will definitely listen to you, I will learn whatever you ask me to learn." Tinsenson immediately agreed.

Not to be outdone, Guo Yan agreed, squinting his eyes and saying.

Next, Ling Yun began to explain, listed the knowledge points of the first chapter in detail, and then told a few example questions.

I have to say that these two girls have very active brains, and Ling Yun can find them out immediately with just a little stroke.

Soon Ling Yun leaned on the chair easily, looking at the two girls doing the questions opposite.

"Okay, you two have a good look here, and after you finish these questions, you can rest, I'll go out for a walk first. If you come back and see that you haven't finished the question, then don't let me tutor in the future. Ling Yun squinted.

"I will definitely do it, Brother Lingyun, go out!" Guo Yan raised his head and said to Ling Yun.

Ling Yun nodded, and then walked out directly.

The sun was shining outside, and Ling Yun looked at the scene outside.

He still knows a lot about the careful thinking of the two girls.

If Liu Cheng knew that now that he had run over here and taught the two girls homework, I am afraid he would be able to die of laughter.

Thinking of this, Ling Yun shook his head slightly.

After just two circles, Ling Yun was suddenly slightly stunned, and saw that the red LED display in front of him seemed to be displaying his name.

At first, Ling Yun thought that he was dazzled, but when he looked closely, it was indeed his name, which was very large and displayed in front.

Passers-by don't seem to notice this kind of thing at all.

"What's going on?" Ling Yun stepped forward.

Walking to a location, it seems that you can just see the words behind the red LED display.

I saw that it was written, "Lingyun, don't forget, these few days, go to Oriental Pearl City." ”

Seeing this, Ling Yun was slightly stunned, it seems that tomorrow is the time for the signing meeting, and the plane ticket is tomorrow morning, how can he forget about this matter.

Ling Yun couldn't help but reach out and pat his forehead, now that he knew, this must be a masterpiece without makeup.

She deliberately did it so that she could see it.

A middle-aged man in front of him shouted loudly, "Are you all a bunch of rice buckets, how can you not even get a display screen, and don't look at what is displayed on it, how do you programmers write programs, you can make this." ”

"We don't know, we just called someone."

"Hey, how is this going to be normal?"

"It's good." The middle-aged big voice seemed to be very puzzled, and after watching it for a long time, he couldn't help but shake his head, "This is really hell." ”

"Then boss, I'm going to call the repair staff to come over."

The boss glared at the person next to him, "Of course you have to call, you must ask them to find out what is the problem, if this situation occurs in the future, how can it be done." ”

"That's good."

When Ling Yun heard this, he couldn't help but laugh and cry, this is a masterpiece without makeup, go see her tonight and ask about tomorrow, thinking of this, Ling Yun couldn't help but shake his head.

In the plane trading platform, you can control the entire network in the world, and now Su Yan must be watching from a certain camera here, Ling Yun glanced slightly to the side, and then made an ok gesture, indicating that he already knew, but it was not clear if Su Yan could really understand it.

Just as he was about to turn around and go back, Ling Yun heard a voice from behind.

"Brother Lingyun, what are you looking at?"

Ling Yun turned around and saw two girls, standing behind them prettyly, and under the sunlight, those two little faces were tender and could pinch out the water. (To be continued......)
