Chapter 693 (1/2)

Author: Filthy

After Ling Jue finished writing, she walked off the stage. Li Yue was stunned, and so were the others. She had learned it just like that?

Teacher Li had only explained half of the solution just now, but Ling Jue had learned it just like that? ! !

Li Yue coughed lightly. “Ahem, student Ling Jue did a good job. Let’s continue. ”

Ling Jue continued to stare at the blackboard in a daze.

This time, even if Li Yue knew that he was in a daze, she did not ask him to answer the question.

He did indeed know how to..

After cla.s.s, Ling Jue flipped through the math book randomly and memorized all the things inside.

Lu Yilie turned his head and handed him a question. “Lord Jue, solve this question that has been bothering me for years. ”

Ling Jue raised an eyebrow at him and took his question. “This is a middle school math question, right? ”

He looked pitiful. “Yes, I’ve been bothering you with this question for years. YX has already set it up. I’ve never solved it before. I once suspected that this question was wrong, but the pattern doesn’t seem to be wrong. SOLVE IT! ”

Ling Jue glanced at him indifferently “set the focus of Parabola 042 & amp; Gt; a ax Y to be a, with B a + 4,0 points as the center of the circle, and Ab as the radius. Draw a semicircle above the x axis, and set the intersection of Parabola and semicircle with two different points M, N. Point P is the middle point of MN. 1 Request Am + an Fu’s value… … …”

Ling Jue took out a pen and began to write, “look here. Solve 1 and set M, N, P. The projectiles on the Parabola’s quasi-line are M �� , N �� , P �� . Am + an Fu’s mm �� + f n �� x m + X N + 2A, and the circular equation is 16422 + +-Y A X…. ”

Lu Yilie was dumbfounded when he saw Ling Jue’s hand quickly writing on the paper. “This works? ”

“Yes, you didn’t see the main point of the question. This is p, the midpoint of MN. You’re thinking too much. ”

“…”

Lu Yilie took the paper from him and returned to his seat to study it.

After a moment, he immediately cried out, “Lord Jue! I understand now! HAHAHA! ”
