किस मान पर ((m-4)x-3+7x-2) रेखीय बहुपद बनेगा?
For which value will ((m-4)x-3+7x-2) become a linear polynomial?
Explanation opens after your attempt
B. (m=4)
Concept
To become linear, the coefficient of \(x^3\) must be (0). From (m-4=0), we get (m=4).
Why this answer is correct
The correct answer is B. (m=4). To become linear, the coefficient of \(x^3\) must be (0). From (m-4=0), we get (m=4).
Exam Tip
रेखीय बनने के लिए \(x^3\) का गुणांक (0) होना चाहिए। (m-4=0) से (m=4) मिलता है।
