किस मान पर ((m-6)x-5+2x-2+7) की डिग्री (2) होगी?
For which value will the degree of ((m-6)x-5+2x-2+7) be (2)?
Explanation opens after your attempt
A. (m=6)
Concept
For degree (2), the coefficient of \(x^5\) must be (0). From (m-6=0), we get (m=6).
Why this answer is correct
The correct answer is A. (m=6). For degree (2), the coefficient of \(x^5\) must be (0). From (m-6=0), we get (m=6).
Exam Tip
डिग्री (2) के लिए \(x^5\) का गुणांक (0) होना चाहिए। (m-6=0) से (m=6) मिलता है।
