यदि (p(x)=(a+3)x-2+5x-1) रैखिक बहुपद है, तो (a) क्या होगा?

If (p(x)=(a+3)x-2+5x-1) is a linear polynomial, what is (a)?

Explanation opens after your attempt
Correct Answer

A. (-3)

Step 1

Concept

For it to be linear, the coefficient of \(x^2\) must be (0). Hence (a+3=0) and (a=-3).

Step 2

Why this answer is correct

The correct answer is A. (-3). For it to be linear, the coefficient of \(x^2\) must be (0). Hence (a+3=0) and (a=-3).

Step 3

Exam Tip

रैखिक होने के लिए \(x^2\) का गुणांक (0) होना चाहिए। इसलिए (a+3=0) और (a=-3)।
