किस मान पर ((m+5)x+7) रेखीय बहुपद नहीं रहेगा?
For which value will ((m+5)x+7) not remain a linear polynomial?
Explanation opens after your attempt
C. (m=-5)
Concept
To be linear, the coefficient of (x) must not be zero. At (m=-5), (m+5=0).
Why this answer is correct
The correct answer is C. (m=-5). To be linear, the coefficient of (x) must not be zero. At (m=-5), (m+5=0).
Exam Tip
रेखीय होने के लिए (x) का गुणांक शून्य नहीं होना चाहिए। (m=-5) पर (m+5=0) हो जाता है।
