God-level ancient martial arts master

Chapter 39
When Xia Yixin was concentrating on solving the problem, the profile of her face was like a small red apple, drooping and dripping, making people feel an urge to pounce on it and take a bite.

The faint body fragrance that is unique to a girl blows over her face.Lin Yu instinctively sucked his nose, fascinated.

"Okay, let's see first..."

Because Lin Yu was too close, Xia Yixin turned around, and the two of them were face to face, almost in zero distance contact.

Xia Yixin's flushed little face was so embarrassing that she almost bled.

Afterwards, she turned around quickly and buried her head very low to cover up her shyness and embarrassment just now.

Lin Yu was also a little embarrassed, smiled embarrassingly, and said, "Yixin, thank you!"

"It's okay, just look at it yourself, and ask me if you don't understand!" Xia Yi replied in a low voice without raising her heart.

Lin Yu responded casually, and took the problem-solving process given by Xia Yixin, and looked at it seriously.

However, he only took it seriously for three seconds.

Actually, it doesn't mean that he's hot for 3 minutes, no, it's [-] seconds of heat.It was the first equation that stumped him.

"Yixin, I don't understand this, please help me look!"

Looking at the direction of Lin Yu's finger, Xia Yixin stared round with big watery eyes, and asked with a little surprise: "This is a one-dimensional equation, the content of the first grade of junior high school, don't you know it too?"

Lin Yu pretended to be surprised and replied: "Uh, isn't it a quadratic equation in one yuan? Why is it a linear equation in one yuan again? It can't be inflation, is it a price increase?"

Hearing Lin Yu's answer, Xia Yixin was taken aback for a moment, then covered her mouth and giggled.

"Lin Yu, you are so funny!"

Lin Yu scratched his head in embarrassment, and said, "Just kidding, but I really don't understand what is a one-dimensional linear equation and what is a one-dimensional quadratic equation. Tell me about it!"

Although Xia Yixin felt a little unbelievable, seeing Lin Yu's expression did not seem to be joking, she tapped lightly and wrote down an equation on the paper: x+a=b!

Then, she pointed to the letter [x] with the tip of her pen and said: "Lin Yu, look, this equation is a one-dimensional equation. It contains an unknown number, the degree is 1, and the left and right are equal."

Hearing Xia Yixin's explanation, Lin Yu suddenly realized, nodded vigorously, and replied: "Oh, so that's the case, I understand. What about the quadratic equation in one yuan?"

Xia Yixin's bright eyes blinked lightly, and then she wrote another equation on the paper: ax?+bx+c=0 (a≠0).

Seeing this equation, Lin Yu clicked his lips subconsciously, and muttered secretly in his heart: Fuck, abc works together, and x has opened a square, it seems that cheap is really not good!
Xia Yixin seemed to see through Lin Yu's mind, smiled, and said: "A quadratic equation in one yuan is slightly more difficult than a linear equation in one yuan. An integer equation that only contains one unknown and the highest degree of the unknown item is 2. It’s called a quadratic equation.”

"There are generally four ways to solve such an equation, namely, the direct derivation method, the compound method, the formula method, and the factorization method. I just used these four solution methods to write you the process of solving the problem."

After listening to Xia Yixin's explanation, Lin Yu felt his head was a little big.It is really difficult for him to understand the important and difficult content of the third grade of junior high school with his mathematics level in the third grade of primary school.

However, under the patient guidance of Xiaohua Xueba, Lin Yu finally figured out what a quadratic equation in one yuan is.However, when he heard that there was a quadratic equation in the first year of senior high school, he missed his elementary school math teacher a little bit!
On the third day when Lin Yu came to school, he quietly entered the village after taking the exam.

In addition to Chinese and history, the multiple-choice questions of other subjects, ABCD four options, whichever one is pleasing to Lin Yu's eyes, will be lucky.

Two days later, the results came out.

Xia Yixin is worthy of the title of "School Girl". She actually scored 150 points in the 148-point math paper.The total score is 669, ranking first in the grade.

Bingshan school flower Ye Xiaoya is also a veritable top student. Although she is not as good as Xia Yixin in mathematics, she is the best in English. In the end, she came in second with a difference of 3 points.

No.3 is a man with glasses named Yang Hao, with a total score of 644...

Lin Yu didn't care much about grades. He lay on the table alone, looking at all kinds of students in the class boredly.

"Brother, how many points did you get?" Lin Wan'er ran to Lin Yu with a strawberry lollipop in her mouth, and asked with a smile.

Lin Yu raised his eyebrows and asked, "how many points did you get?"

Lin Wan'er pouted, and replied casually, "You didn't do well in the exam, you only got 632 points."

"Fuck, it's only 632 points, are you still letting other people live?"

"Hey, brother, let me see how many points you got in the test!" Lin Wan'er's clear eyes blinked in the air, and a sly smile appeared.

Lin Yu curled his lips and responded casually: "Go play while I'm too lazy to talk to you!"

"Brother, can you tell me?" Lin Wan'er grabbed Lin Yu's arm, swung it back and forth a few times, and began to act coquettishly.

Qian Haining, who was not far away, saw this scene, and his teeth were almost gnawed to pieces in anger.Those dark eyes were full of raging flames.If eyes can kill, then Lin Yu's classmate at this time may have been burnt to the point that there is not even a scum left.

At this moment, the dog leg Shen Xu ran over, and said with a flattering smile: "Qian Shao, congratulations, you are not the last one in this mock exam!"

Qian Haining's total score in the senior high school entrance examination was only 200 points, and he was admitted to the key class because of his family relationship.Moreover, he is only interested in Lin Wan'er, and the rest doesn't matter, the exam depends entirely on his mood.

Therefore, in Class [-] where there are so many top students, he is the last one every time.In the past three years, no one can shake the throne at the tail of the crane.

Hearing that he was no longer the tail of the crane, Qian Haining immediately became interested, and asked casually; "Then who is No. 1?"

Shen Xu deliberately raised his voice a little, and replied: "Who else is it? Of course it is a fighter among the scumbags, Lin Yu, this guy only scored 249 points in the exam, and you are 1 point less than money, really I wonder if there is something wrong with his brain, even if another idiot takes the test, he will definitely be able to score more than 300 points in the test."

When Qian Haining heard the first half of the sentence, he felt very happy. It is really rare to see scumbags with worse grades than himself these days.

However, when he heard the second half of the sentence, he felt something was wrong.An idiot can score more than 300 points in the test, but he only scored 250 points in the test. Isn't that worse than an idiot?
Thinking of this, Qian Haining grabbed the textbook in front of him, threw it at Shen Xu's head, and cursed: "Fuck, Shen Xu, your uncle is an idiot, your whole family is an idiot!"

At this moment, Liu Qing, the beautiful class teacher, walked into the classroom with an English book, knocked on the desk hard, and shouted loudly: "Everyone, please be quiet in your seats. Next, we will hold a class meeting." !"

　Xiao Le, I am a top student, do you believe it, believe it or not, believe it or not?Ma Dan, in order to understand what is a linear equation in one variable and a quadratic equation in one variable, I searched a lot of information and asked a lot of people. A junior high school math teacher just vomited blood and died! ! !Here, in the name of a math teacher, Xiao Le yelled three times in the air: Please recommend a ticket, ask for a reward, and ask for a collection! ! !
