किस मान पर (\(r^2-2r\)x+9) रेखीय बहुपद नहीं रहेगा?
For which value will (\(r^2-2r\)x+9) not remain a linear polynomial?
Explanation opens after your attempt
A. (r=0) या (r=2)(r=0) or (r=2)
Concept
For it not to be linear, the coefficient of (x) must be (0). (r-2-2r=r(r-2)=0) gives (r=0) or (r=2).
Why this answer is correct
The correct answer is A. (r=0) या (r=2) / (r=0) or (r=2). For it not to be linear, the coefficient of (x) must be (0). (r-2-2r=r(r-2)=0) gives (r=0) or (r=2).
Exam Tip
रेखीय न रहने के लिए (x) का गुणांक (0) होना चाहिए। (r-2-2r=r(r-2)=0) से (r=0) या (r=2) मिलता है।
