Fang Chao's math papers in advance did not affect other people's judgment of him. A poor student is a poor student, and he can become a top student by listening carefully.

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

After the monthly exam, there are two other exams, Chinese and English.

The so-called monthly exam does not take the results of physics, chemistry, biology, etc., but mainly refer to your main subjects. These three are important items. Moreover, the monthly exam is only given to you by the teacher alone. Unlike the midterm exam or final exam, the entire school will take the exam together.

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

Fang Chao thought, should he improve his skill points first at the beginning? Because he understood more about mathematics.

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

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

He patted a thick stack of test papers on the podium, and then said, "The test papers I gave this time are a bit difficult, but they shouldn't be too difficult. There is only one person in your class who gave me a full mark. What's wrong with the others?"

"Liu Qian, as the deputy class monitor in the class, you just got 132 in math this time. There are some places where you shouldn't be wrong and you made it wrong for me."

Liu Qian is very white, not tall, with a little baby fat, with a pair of silver wire 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 still divided the test papers into five parts and then asked someone to help distribute the test papers.

When the test paper was assigned to Fang Chao, the student who distributed the test paper was obviously stunned, "Teacher."

"Um?"

"Is there a mistake in Fang Chao's test paper? Teacher, didn't you say that there is only one person in the class who has full marks in math scores? Shouldn't this person be Lin Kai? Why is Fang Chao full marks? Did he approve the wrong one?"

"What?" Zhang Yangjian was also stunned and took Fang Chao's test paper and took a look, "Damn, what's the situation with you? Is this red 150 your score?"

On the other hand, Lin Kai, who is a representative of mathematics, spread his test paper on the table and then said, "That full mark is not me."

His test paper is basically red ‘√’, but there is some difficulty on the last question, and there is not enough time, so he doesn’t have time to answer it. He just made some questions and got a little score. His test score is 146, which is four points away from the full score.

"Teacher, Fang Chao must have cheated."

"Yes, I must have cheated, otherwise, how could he get the full mark? And he also handed in the paper in advance."

“…”

Almost all the students in the class questioned Fang Chao.

Even Zhang Yangjiandu looked at Fang Chao with some suspicion, "You kid won't really cheat, right? It shouldn't be that you're just like me and you're just blind cats and dead rats. You don't even understand those formulas. How could you copy them? Besides, go where to copy them if you copy them?"

Fang Chao gave Zhang Yangjian a blank look. If I want to copy, I won’t choose C.

The whole classroom is noisy and it is difficult to calm down.

Lin Haifeng shouted, "Does he still have the face to make noise after completing this exam?"

In an instant, the classroom suddenly became quiet.

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 a good grade by yourself? OK, then tell me, Fang Chao plagiarized, who did he plagiarize? Who did you give me the full score?"

"this……"

"Teacher, he must have copied the answers in the book."

"Will the test paper be leaked in advance?"

Lin Haifeng said again, "I know that many people will think that Fang Chao cheats, but I want to tell you that there is no shortcut in mathematics. It is not like English or Chinese. No one can do it overnight. Mathematics requires a high enthusiasm for it. Only with true love can you achieve good results. Over the past month, I believe everyone has seen changes in Fang Chao. He has basically not slept in class and has not done anything else."

"Teacher, it's not all. When he returned to the dormitory after class, he was also studying hard alone, and took out the algebra and geometry textbooks for the first and second grades of junior high school."

"Yes, we told him to go out to play with us on weekends and he didn't go out anymore. He just kept reading with his textbook every night. Anyway, when we saw him, he basically never separated from these..."

Several Fang Chao's roommates stood up for him at this time. They saw Fang Chao's efforts and were not allowed to be slandered.

Everyone’s efforts should be worthy of respect!

"I see."

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

"Is this a genius... I think he basically didn't study in the first grade of junior high school and the second grade of junior high school. In just about a month, can he actually get the first place in mathematics?"

Lin Haifeng nodded with great satisfaction. What he could be proud of was not the top student in the class, but the poor student turned into a top student. This is the most proud thing. When I go out, I can also boast that there was a student in our class who used to be the countdown in mathematics in the class, but through hard work, with my help, he got the first place in mathematics in the class!

How awesome!

This is my student of Lin Haifeng, and it is my pride!

None of you have such a student.

Then, Lin Haifeng said again, "Some people, without the outbreak, will never know how powerful he is. I know that there are many people who will doubt the authenticity of this exam and have some doubts about Fang Chao's scores. Well, Fang Chao, come up and answer the last answer question on the math test paper."

"good."

Fang Chao stood up. At this moment, he felt that all the eyes of the people around him were on him.

It is no longer ignorance, no longer ridicule, but more envy and admiration.

It’s like I used to see Lin Kai, or the top students in the class.

It turns out that one day I can enjoy such a gaze.

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

When a is the value, the polynomial x27xyay25x43y24 can be decomposed into the product of two primary factors.

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

Fang Chao understood the meaning of black-faced carbon. He wanted to prove himself and tell others that he was not plagiarizing, but that he was a real result!

He quickly took out the chalk. He would have no choice but to do it before, but now he is familiar with all these things and is really not difficult at all.

x27xyay25x43y24=(xkyc)(xlyd)(Decomposition factor)

∵(xkyc)(xlyd)=x2(kl)xykly2(cd)x(cldk)ycd

∴    cd=24,cd=5

∴     c=3,d=8

∵     cldk=43

∴   3l-8k=43

∵    kl=7

∴    k=-2,l=9

∴    a=kl=-18

"What is this? He did not do anything wrong? Why can't I understand it?"

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

The person next to him touched Lin Kai and said, "Is that so? Is there anything wrong?"
Chapter completed!
