किस मान पर ((k+4)x-2+3x-9) रेखीय बहुपद बनेगा?

For which value will ((k+4)x-2+3x-9) become a linear polynomial?

Explanation opens after your attempt
Correct Answer

B. (k=-4)

Step 1

Concept

To become linear, the coefficient of \(x^2\) must be (0). From (k+4=0), we get (k=-4).

Step 2

Why this answer is correct

The correct answer is B. (k=-4). To become linear, the coefficient of \(x^2\) must be (0). From (k+4=0), we get (k=-4).

Step 3

Exam Tip

रेखीय बनने के लिए \(x^2\) का गुणांक (0) होना चाहिए। (k+4=0) से (k=-4) मिलता है।
