Chapter 1 I'm Serious About Solving Problems
Beishan No. [-] Middle School, mathematics classroom.
Li Wei's face was livid, and he stared straight at Qin Luo: "Qin Luo, get up, tell me how to solve this problem?"
While talking, Li Wei casually wrote a mathematical equation on the blackboard.
He dared to sleep in his class, he just didn't know how to write dead words.
"It is known that the ellipse X square + Y square = 1 and the straight line X-Y + B = 0 intersect at two points PQ, O is the coordinate origin, if OP is perpendicular to OQ, find the value of B, and write the process."
Qin Luo's chrysanthemum tightened her face in bewilderment.
"The strongest student master system is activated, and the progress is 99%..."
"The system installation was successful."
who?Who is talking?Qin Luo looked around.
"Hey, the host thinks carefully and gets 1 point of mastery."
system!At this moment, Qin Luo became excited, as an old bookworm in the 21st century, he was too familiar with things like the system.
This is a must for the protagonist, and those who get him, without exception, become awesome existences.
It's just that Qin Luo didn't expect that he also got the system
Thinking of this, Qin Luo's heart beat faster.
"Don't stand still, do it quickly!"
"Do you think you are a genius, like Huang Xing, who can get full marks in class and sleep?"
Huang Xing, the son of the dean of No. [-] Middle School, from the moment he stepped into No. [-] Middle School, he was a true favorite. His academic performance has never been in the top three. Save the top [-].
He has always been the sharpest weapon in Li Wei's mouth.
"Isn't it just a question? It's not like you can't do it." Qin Luo glanced at Li Wei confidently, and walked straight to the podium.
Starting today, he is no longer an ordinary person, but a person with a system.
Picking up the chalk, Qin Luo suddenly found himself in trouble. Although he had a system, he didn't know how to use it.
"Mr. Li is one of the top ten math teachers in the city. Even I am not sure about the questions he asked, him? Hehe, give him ten days, and he won't be able to get it right." Huang Xing pulled his eyes and glanced lightly. Qin Luo glanced at her with disdain.
For this question, he only needs 10 minutes to solve it, but for Qin Luo?Perhaps it is a ditch that is insurmountable in a lifetime.
"Hahaha, Qin Luo, do you want to show you the notes of our handsome guy Huang? Maybe you can find a solution to the problem?"
"..."
For a while, the classroom was full of laughter and laughter.
"The rapid death of host brain cells is detected, and the system automatically calculates a solution."
"Study master value: 1 point"
Suddenly, a short system beep sounded.The picture in front of Qin Luo's eyes has completely changed. The geometric equation is no longer an incomprehensible astronomical number, but has become extremely simple.
Flying his hands, a series of numbers appeared on the blackboard.
The straight line X-Y+B=0, that is, Y=X+B, let P(X1, X1+B)...
Solved: -√2
Obtained by Veda's theorem: "X1+X2=-B...
Comprehensively get B=1 or b=-1
"Look, Qin Luo has started writing!"
"Ouch, √2 is still well written."
"..."
"So what if you start writing? Mathematics is not English. As long as you write, you can score."
Hearing the movement of the students, Li Wei turned his head slowly.
In the next second, his eyes widened.
The logic is clear, the steps are clear, the process is flawless, and most importantly, the answers are correct.
Qin Luo actually solved the answer!
He knew the difficulty of the questions he asked, even Huang Xing, the top student in the class, had a hard time doing it, let alone Qin Luo.
