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
A. (-3)
Concept
For it to be linear, the coefficient of \(x^2\) must be (0). Hence (a+3=0) and (a=-3).
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).
Exam Tip
रैखिक होने के लिए \(x^2\) का गुणांक (0) होना चाहिए। इसलिए (a+3=0) और (a=-3)।
