Beishan No. 4 Middle School, math class.

Li Wei's face was ashen, and he glared at Qin Luo: "Qin Luo, get up, tell me how to solve this problem?"

As he spoke, 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 origin of the coordinates, if OP is perpendicular to OQ, find the value of B, and write the process."

Qin Luo Juhua's face was full of confusion.

"The strongest scholar system is on, and the progress is 99%..."

"System installation was successful."

who? who is talking? Qin Luo looked around.

"Did, the host thinks hard and gets 1 point of academic mastery."

system! This time, Qin Luo was excited. As an old bookworm in the twenty-first world, he was too familiar with the system.

This is a must for the protagonist, and the people who get him, without exception, have become arrogant existences.

It's just that Qin Luo didn't expect that he actually got the system.

Thinking of this, Qin Luo's heart beat faster.

"Don't be stunned, do it quickly!"

"Do you think you are a genius and can get full marks in class and sleep like Huang Zhen?"

Huang Zhen, the son of the dean of the No. 4 Middle School, has been a true genius from the moment he stepped into the No. 4 Middle School. His academic performance has never been in the top three. Save thousands.

He has always been Li Wei's sharpest weapon.

"Isn't it just a question? It's not like he can't do it." Qin Luo glanced at Li Wei smugly and walked straight to the podium.

From today, he is no longer an ordinary person, but a person with a system.

Picking up the chalk, Qin Luo suddenly got into trouble. Although he had the 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 a little inaccurate about the questions he gave, he? Hehe, he can't do it right for ten days." Huang Zhenla raised his eyes and swept it lightly. Qin Luo glanced at him with disdain in his eyes.

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 I need to show you the notes of our handsome Huang? Maybe, you can find a way to solve the problem?"

"..."

For a time, the classroom was full of laughter.

"The rapid death of the host's brain cells is detected, and the system automatically calculates a solution."

"Consumption of academic hegemony: 1 point"

Suddenly, a short system alert sounded. The picture in front of Qin Luo's eyes has completely changed. The geometric equations are no longer incomprehensible astronomical numbers, but become extremely simple.

With his hands flying, a series of numbers appeared on the blackboard.

Straight line X-Y+B=0, that is, Y=X+B, let P(X1, X1+B)...

Solve: -āˆš2\u003cb\u003cāˆš2

It is obtained from the Veda theorem: "X1+X2=-B...

Comprehensively get B=1 or b=-1

"Look, Qin Luo has started writing!"

"Ouch, āˆš2 also wrote in a similar manner."

"..."

"So what if you start writing? Math is not English, as long as you write, you get points."

Hearing the movements of the students, Li Wei slowly turned his head.

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 came up with. Even the top student in the class, Huang Zhen, struggled to do it, let alone Qin Luo.
