C1 I'm Serious about the Problem

Beishan Fourth Middle School, mathematics class.

Lee Wei's face turned ashen. He stared at Qin Luo and said, "Qin Luo, get up. Tell me, how do you solve this problem?"

While saying that, Lee Wei wrote out a mathematical equation on the blackboard.

He actually dared to sleep in his classroom. He simply did not know how to write the word death.

"Known ellipse X squared + Y squared = 1 and straight line X-Y + B = 0, intersecting PQ 2 points, O is the origin of the coordinates, if OP is perpendicular to OQ, calculate B value, write process."

Qin Luo was completely confused.

"Strongest bookworm activation, progress 99%..."

"System installation successful."

Who is it? Who was talking? Qin Luo looked around.

"Beep, the host seriously thinks about it. You have earned 1 study point."

System! At this moment, Qin Luo became excited. As the bookworm of the 21st world, he was very familiar with the system.

This was a must for the main character. Those who received him, without exception, became all powerful existences.

However, Qin Luo didn't expect that he would get the system as well …

Thinking about that, Qin Luo's heart couldn't help but beat faster.

"Don't just stand there. Do it quickly!"

"Do you think you're a genius who can sleep like Huang Zhen?"

Huang Zhen, the son of the Fourth Middle School Teaching Director. From the moment he stepped into Fourth Middle School, he was truly a favored son of heaven, and his academic performance had never been ranked in the top three. Every time he took the entrance exam, he was placed in the top ten of the city, with hundreds of thousands of people in the province.

He had always been the sharpest weapon in Lee Wei's mouth.

"Isn't it just a question? It's not like I don't know how to do it. " Qin Luo glanced at Lee Wei with complacency and walked straight to the podium.

From today onwards, he would no longer be an ordinary person, but someone with the system.

Picking up the chalk, Qin Luo suddenly felt troubled. Although he had the system, he didn't know how to use it.

"Teacher Lee is one of the top ten math teachers in the entire city. "Hehe, even if you give him ten days, he still won't be able to do the right thing." Huang Zhen's eyes narrowed as he indifferently swept a glance at Qin Luo. His gaze was filled with disdain.

For this question, he only needed ten minutes to solve it. But for Qin Luo? Perhaps it was an insurmountable gap in his life. A ravine.

"Hahaha, Qin Luo, do you need me to let you take a look at our handsome brother Huang's notes? Maybe you can find a way to solve this question? "

"…"

For a moment, the entire classroom was filled with cheers and laughter.

"Detected the rapid death of the host's brain cells, the system automatically came up with a solution."

"Exhaustion Study Achievement Point: 1 point"

Suddenly, a short system notification rang out. The scene in front of Qin Luo's eyes had completely changed. The geometric equation was no longer an astronomical number, it had become extremely simple.

A series of numbers appeared on the blackboard.

Line X-Y + B = 0, that is Y = X + B, set P (X1, X1 + B)...

The answer is: - 2 b 2

"X1 + X2 = -B..."

Synthesized B = 1 or b = -1

"Look, Qin Luo has started writing!"

"Oh wow, it was written so well."

"…"

"So what if you started writing? Mathematics is not English. As long as you write it, you can score. "

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

In the next second, he opened his eyes wide.

Logic was clear, steps were clear, and the process was perfect. Most importantly, the answer was correct.

Qin Luo actually did the answer!

He knew the difficulty of the questions he had set. Even the class's top student, Huang Zhen, was having a hard time with them, let alone Qin Luo.
