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

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

Explanation opens after your attempt
Correct Answer

A. (1)

Step 1

Concept

For a constant polynomial, all variable-term coefficients must be zero. From (a-1=0), (a=1), and (5) remains.

Step 2

Why this answer is correct

The correct answer is A. (1). For a constant polynomial, all variable-term coefficients must be zero. From (a-1=0), (a=1), and (5) remains.

Step 3

Exam Tip

स्थिर बहुपद के लिए सभी चर पदों के गुणांक शून्य होने चाहिए। (a-1=0) से (a=1) मिलता है और (5) बचता है।
