किस मान पर ((m+6)x-4-2x+9) रेखीय बहुपद बनेगा?
For which value will ((m+6)x-4-2x+9) become a linear polynomial?
Explanation opens after your attempt
B. (m=-6)
Concept
To become linear, the coefficient of \(x^4\) must be (0). From (m+6=0), we get (m=-6).
Why this answer is correct
The correct answer is B. (m=-6). To become linear, the coefficient of \(x^4\) must be (0). From (m+6=0), we get (m=-6).
Exam Tip
रेखीय बनने के लिए \(x^4\) का गुणांक (0) होना चाहिए। (m+6=0) से (m=-6) मिलता है।
