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