किस मान पर ((r-9)x-3) रेखीय बहुपद नहीं रहेगा?
For which value will ((r-9)x-3) not remain a linear polynomial?
Explanation opens after your attempt
B. (r=9)
Concept
To be linear, the coefficient of (x) must not be zero. At (r=9), (r-9=0).
Why this answer is correct
The correct answer is B. (r=9). To be linear, the coefficient of (x) must not be zero. At (r=9), (r-9=0).
Exam Tip
रेखीय होने के लिए (x) का गुणांक शून्य नहीं होना चाहिए। (r=9) पर (r-9=0) हो जाता है।
