किस मान पर ((2a+6)x-4+5x-2-1) की डिग्री (2) होगी?
For which value will the degree of ((2a+6)x-4+5x-2-1) be (2)?
Explanation opens after your attempt
C. (a=-3)
Concept
For degree (2), the coefficient of \(x^4\) must be (0). From (2a+6=0), we get (a=-3).
Why this answer is correct
The correct answer is C. (a=-3). For degree (2), the coefficient of \(x^4\) must be (0). From (2a+6=0), we get (a=-3).
Exam Tip
डिग्री (2) के लिए \(x^4\) का गुणांक (0) होना चाहिए। (2a+6=0) से (a=-3) मिलता है।
