"Known function f(x)=ax4-x21/2......"

"This question examines the existence theorem of the zero point of the function, the nature of inequality, and the difficulty is medium ......"

The electric fan was whining, sitting side by side with Mu Xiaoxiao, and Guan Ming was talking about the solution in detail. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Mu Xiaoxiao regretted his college entrance examination in his last life, since Guan Ming became her tutor, he naturally would not chat with her or study or anything, although Guan Ming would feel that he was not perfect that day when he slept every day, but he hoped that Mu Xiaoxiao would have a perfect life, a past with no regrets, or few regrets.

Today is the second time Guan Ming has come into contact with Mu Xiaoxiao in his life, he has heard of her past in his previous life, combined with the present, she is really as she said in her previous life about her self-evaluation of her high school days, in good words, it is wooden, upright and obedient, to put it bluntly, it is wooden, axe and obedient......

Wearing fat brown pants that reached the knee and a T-shirt on the upper body, she would only say 'Teacher Guan is good' when they met, and then began to ask questions, although Guan Ming did not deny how hard she worked on her studies, but he was very skeptical that this effort would pay off in the end.

Last time, that is, when she came to tutor for the first time, Guan Ming re-explained her final exam paper to her, although Guan Ming always felt that she was an idiot in mathematics, but looking at the bloody scores, Guan Ming felt that she had basically given up treatment in mathematics.

“…… Take a break, take a walk, and walk for ten minutes before studying. "Two hours have passed since the make-up class fee, Guan Ming asked Mu Xiaoxiao to move his body, so as not to overwhelm his body, after all, he was sitting on a stool for two hours, and he really couldn't resist if he hadn't practiced.

"Oh." Mu Xiaoxiao didn't have the spirit of resistance, put down the ballpoint pen, beat her knees with her little fist, and breathed a small sigh of relief, for mathematics, even if she worked hard for so many years, she still had a frustrated mood.

Guan Ming didn't know if she was frustrated with math or relaxed and tired.

The sound of the TV outside the door of the room is very small, but it is not nothing, after all, the sound insulation of the door of the room is very poor, Guan Ming thinks that this sound is Mu Ma reminding him not to make small moves, although the Mu family does not have a computer now, but it is estimated that he has not heard the story of a bad tutor.

"Get up and take a walk, sit for a long time and feel uncomfortable, just take a breath of high-altitude air." Seeing that Mu Xiaoxiao was lazy on the stool and didn't mean to get up, Guan Ming teased.

“…… Oh......" Flat mouth, Mu Xiaoxiao got up reluctantly, and the range of walking was only less than three meters in the room, two steps and one twisting the waist, three steps and one turn......

"How's the school going? What do you find difficult in your homework? Although I am only your tutor, I still have some basic knowledge of liberal arts. Watching Mu Xiaoxiao jumping out word by word, Guan Ming couldn't say anything else, he felt that if he said some gags now, he could only get an 'oh' word.

"The words of school are okay, it is much easier than the previous class, and the homework is nothing, but I have to memorize a little more." Mu Xiaoxiao said dryly.

In terms of time, it is now a summer vacation make-up class, and the school organizes it, but the time is easier than the normal school, there is no morning reading and evening self-study, every day is a big class of half an hour, and then half a day on Saturday morning, and that's it.

"Have you thought about which school to apply for next year?" Guan Ming had nothing to say to chat.

This week, Mu Xiaoxiao's school just took this year's college entrance examination papers, Guan Ming looked at Mu Xiaoxiao's report card, if the math scores are removed, let alone the class, the age must be counted from the front, but if mathematics is counted, it will be a bit miserable.

Guan Ming rarely observed the proportion of female classmates in the same period, but I have to say that Mu Xiaoxiao did very well in all aspects except mathematics.

"I didn't know that my grades were so bad." Frustrated, he sat back on the stool, scratching his head in frustration.

"The difference is only relative, if you don't look at mathematics, your grades are at your disposal in all universities and majors in China, so what you have to do now is to get your math scores on the premise of ensuring that you don't get grades in other subjects."

"At the same time, you are poor in math, but on the contrary, there is a lot of room for improvement, take this week's test, you have five more points in English and you will get a full score, but you can get more than fifty points in math...... It's not hard. ”

Well, Guan Ming almost said 'That's it', although it was all the truth, he felt that it was difficult for Mu Xiaoxiao to accept this kind of language impact.

With a math score of more than 50 points, Guan Ming doesn't know if Mu Xiaoxiao was beaten, if Guan Ming dared to score 50 points in mathematics, and it was a paper with a full score of 150, he promised that Guan Dad could hang him up and beat him, and then Guan Ma would beat him on the ground again, and finally there would be a mixed doubles.

"But math is so difficult, I understand it after you and the teacher finish it, but when it comes to doing problems, I won't ......" His chin rested on the desk, and his head fell together when he spoke, Mu Xiaoxiao hung his head like a waste.

"Hmm...... Can I memorize the formula? I'm talking about the base formula. Although this is a perfect moment to pour chicken soup, Guan Ming feels that standing at a certain height and saying something above is a kind of distance in itself, and he doesn't want to really be Mu Xiaoxiao's teacher, distance or something.

"Probably, but it's always easy to get confused." Scratching his head, Mu Xiaoxiao's voice was full of confusion.

"Then how do you memorize other subjects, history, geography." Guan Ming is more puzzled by her brain circuit, normally speaking, even if she is biased, she will not be biased to this extent, which is also what Guan Ming has always been more puzzling, because there must be a limit to the bias of the subject, if the score of one subject is half or even less than half of the other, this is already considered serious, but Mu Xiaoxiao's English is more than twice and three times faster than her mathematics, and her score is no longer lame, this is simply an amputation.

"There are clear answers to those subjects, for example, the reluctance of the Romans to give the right to obtain legal protection to outsiders, which shows that Rome has a strong closed character."

"Another example is the geological environment rich in organic matter, which can generate and discharge a large amount of oil and gas, and generally has a large number of biological deposits."

"But a lot of math is a lot of things that go around and around, and I can't understand it." Mu Xiaoxiao's whole face slammed on the table, and she was in the stage where she had no face to see anyone.

"Hmm...... Personally, I feel that mathematics is easier than politics, because in addition to the understanding of the problem stem, the rest can be handled step by step with formulas, so let's sort out the mathematical formulas for you, you must first memorize all the formulas, and then learn to apply the formulas. Although Guan Ming wants her to deal with math problems more simply, but from the current point of view, she is better at memorizing, as for why politics, the field or something is clear in her eyes, Guan Ming said that he is not clear, after all, brain circuits are like Hamlet, individual differences more or less exist.
