Fang Chao's mathematics paper was handed in ahead of schedule, which did not affect other people's judgment of him, a scumbag is a scumbag, and he can become a top student if he doesn't listen carefully to the class.

Even his sworn friend Zhang Yangjian is not optimistic about Fang Chao, let alone others.

After the month-end exam, there are two other exams, Chinese and English.

The so-called month-end exams do not test physics, chemistry, biology and the like, but mainly refer to your main subjects, which are important items, and the month-end exams are just the teachers who give you the test papers alone, unlike the mid-term exams or final exams, the whole school takes the test together for the whole year.

For Fang Chao, who submitted the math exam in advance, he did not submit the papers in Chinese and English early, which was very embarrassing and still not easy, he was not too good at these two subjects, and the skill points were not added to these two credits.

Fang Chao thought to himself, shouldn't he have improved his skill points at the beginning? Because he understands a little bit more about mathematics.

However, the remaining top students did not have enough points, and Fang Chao gave up this idea.

The next day, during math class, Lin Haifeng walked into the office with a calm face.

He slapped the thick stack of test papers on the podium, and then said, "This time my test papers are a bit difficult, but it shouldn't be too difficult, only one of you in the class gave me a perfect score, what about the others?" ”

"Liu Qian, as the deputy head of the class, you actually only took the 132 test in mathematics this time, and you made a mistake for me in some places that shouldn't be wrong."

Liu Qian was very white, not tall, with a little baby fat, a pair of silver eyes hanging above the bridge of her nose, she lowered her head and whispered, "I'm sorry." ”

Lin Haifeng wanted to say something, but after thinking about it, he divided the test papers into five parts, and then asked people to help distribute these test papers.

When the test papers were assigned to Fang Chao, the students who distributed the test papers were obviously stunned for a moment, "Teacher." ”

"Huh?"

"Did Fang Chao's test paper go wrong? Didn't you say that only one person in the class got a perfect score in math? Shouldn't this person be Lin Kai? Why is Fang Chao a full score, is it a mistake? ”

"What?" Zhang Yangjian was also stunned, and glanced at Fang Chao's test paper, ", what's the situation with you kid, is this red 150 your score?" ”

On the other side, Lin Kai, as a representative of mathematics, spread his test paper on the table, and then said, "The perfect score is not me." ”

His test paper was basically red '√', but there was some difficulty on the last question, and there was not enough time, so he didn't have time to answer it, he just made some steps to solve the question, and got a little score, and his test score was 146, four points away from the full score.

"Teacher, Fang Chao must have cheated."

"Yes, he must have cheated, otherwise, how could he have scored a full score, and he also submitted the paper in advance."

“……”

The whole class almost questioned Fang Chao.

Even Zhang Yangjian looked at Fang Chao with some suspicion, "You kid won't really cheat, right?" It shouldn't be, you're either a blind cat like me and a dead mouse, you don't even know those formulas, how can you copy it, besides, if you copy it, where to copy it? ”

Fang Chao glanced at Zhang Yangjian here, if I want to copy, I won't choose C.

The whole classroom was noisy and it was hard to calm down.

Lin Haifeng shouted, "Do you still have a noisy face after passing this test?" ”

In an instant, the classroom fell silent.

Black-faced Carbon has absolute majesty in this regard, and no one dares to disobey him.

Immediately afterwards, Lin Haifeng spoke again, "Why should you question others if you can't get good grades in the exam?" Okay, then you tell me, Fang Chao plagiarized him, who did he copy? Did any of you give me a perfect score? ”

"This ......"

"Teacher, he must have copied the answer from the book."

"Could it be that the exam papers were leaked in advance?"

Lin Haifeng said again, "I know, many people will think that Fang Chao cheats, but I want to tell you that there is no shortcut to mathematics, it is not like English, not like Chinese, no one can achieve it overnight, mathematics needs to have a high enthusiasm for it, only true love, can produce good results, this month, I believe everyone has seen Fang Chao's changes, he basically didn't sleep in class, and he didn't do anything else." ”

"Teacher, that's not all, when he returned to the dormitory after class, he also buried himself in hard reading, and took out the math textbooks for the first and second years of junior high school."

"yes, we asked him to go out on weekends to play with us, he didn't go out, he was reading with his textbook every night, anyway, when we saw him, he basically didn't have to be separated from these......"

Several of Fang Chao's roommates were fighting for him at such a time, and Fang Chao's efforts were seen in their eyes and were not allowed to be slandered.

Everyone's efforts deserve to be respected!

"I see."

"I didn't expect Fang Chao to be so diligent......"

"Isn't that genius...... I see that he basically didn't study in the first and second years of junior high school, and in just about a month, he was able to get the first place in mathematics? ”

Lin Haifeng also nodded with great satisfaction, he can be proud of not the top student in the class, but the scumbag has become a top student, this is the most proud thing, and when he goes out in the future, he can also boast that there was a student in our class before, he used to be the bottom of the class in mathematics, but through his hard work, with my help, he was admitted to the first place in mathematics in the class!

What a coaxing and coaxing

This is my Lin Haifeng's student, and I am proud!

None of you have such students.

Then, Lin Haifeng spoke again, "Some people, if he doesn't break out, others will never know how powerful he is. I know that there are still many people who will doubt the authenticity of this exam and have doubts about Fang Chao's results, so okay, Fang Chao, you come up and answer the last answer question on the math exam paper. ”

"Okay."

Fang Chao stood up, and at this moment, he felt that all the eyes of the people around him fell on him.

No longer ignorance, no more ridicule, more envy, admiration.

It's like watching Lin Kai in the past, just like watching the top students in the class.

It turns out that one day I will be able to enjoy such a gaze.

Lin Haifeng turned around, took out chalk, and wrote down the last question on the blackboard.

The polynomial x2+7xy+ay25x+43y24 can be decomposed into the product of two primary factors when a is what the value is.

Lin Haifeng took Fang Chao's test paper and asked him to write the answer again.

Fang Chao understands the meaning of black-faced carbon, this is to prove himself and tell others that he is not plagiarism, he is a real achievement!

He quickly took out the chalk, which used to be at a loss, but now, he knew it by heart, and it really wasn't difficult at all.

x2+7xy+ay25x+43y24=(x+ky+c)(x+ly+d)(factor)

∵（x+ky+c）（x+ly+d）=x2+（k+l）xy+kly2+（c+d）x+（cl+dk）y+cd

∴ cd=24，c+d=5

∴ c=3，d=8

∵ cl+dk=43

∴ 3l-8k=43

∵ k+l=7

∴ k=-2，l=9

∴ a=kl=-18

"What is this? He didn't do anything wrong, did he? Why can't I understand something? ”

Lin Kai looked at the answer written by Fang Chao and said, "So that's ......."

The person next to him touched Lin Kaidao, "Is that so?" Is there something wrong? ”

Lin Kai shook his head, "That's right, that's the case...... I didn't expect that there really was a genius in this world...... After a month of hard work, he became the first in mathematics in the class. ”
