किस मान पर (\(r^2-9r+20\)x+6) रेखीय बहुपद नहीं रहेगा?
For which value will (\(r^2-9r+20\)x+6) not remain a linear polynomial?
Explanation opens after your attempt
A. (r=4) या (r=5)(r=4) or (r=5)
Concept
For it not to be linear, the coefficient of (x) must be (0). From \(r^2-9r+20=0\), (r=4) or (r=5).
Why this answer is correct
The correct answer is A. (r=4) या (r=5) / (r=4) or (r=5). For it not to be linear, the coefficient of (x) must be (0). From \(r^2-9r+20=0\), (r=4) or (r=5).
Exam Tip
रेखीय न रहने के लिए (x) का गुणांक (0) होना चाहिए। \(r^2-9r+20=0\) से (r=4) या (r=5) मिलता है।
