Chapter 1： Im serious about solving problems (2/2)
For this question, he only needs 10 minutes to do 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 Huang Da? Maybe you can find a way to solve the problem?”
”...”
For a while, the classroom was full of laughter.
”Detecting the rapid death of host brain cells, the system automatically calculates the solution.”
”Study hegemony cost: 1 point”
Suddenly a short system prompt sounded. The picture in front of Qin Luo completely changed, and the geometric equations were no longer incomprehensible astronomical numbers, but extremely simple.
Flicking with both hands, a series of numbers appeared on the blackboard.
The straight line X-Y+B=0, that is, Y=X+B, set P(X1, X1+B)...
Solution: -√2＜b＜√2
Obtained from the Veda theorem: ”X1+X2=-B……
Comprehensively get B=1 or b=-1
”Look, Qin Luo has started writing!”
”Oh, what √2 writes is so beautiful.”
”...”
”What can I do if I write? Mathematics is not English. You can score as long as you write.”
Hearing the movement of the students, Li Wei slowly turned his head.
In the next second, his eyes widened.
The logic is clear, the steps are clear, the process is flawless, and most importantly, the answer is correct.
Qin Luo actually figured out the answer!
He knew the difficulty of the questions he asked. Even the top student in the class, Huang Zhen, was struggling to do it, let alone Qin Luo.
