किस मान पर ((m+1)x-3+5x-6) रेखीय बहुपद बन जाएगा?
For which value will ((m+1)x-3+5x-6) become a linear polynomial?
Explanation opens after your attempt
B. (m=-1)
Concept
To become linear, the coefficient of \(x^3\) must be (0). So (m+1=0) gives (m=-1).
Why this answer is correct
The correct answer is B. (m=-1). To become linear, the coefficient of \(x^3\) must be (0). So (m+1=0) gives (m=-1).
Exam Tip
रेखीय बनने के लिए \(x^3\) का गुणांक (0) होना चाहिए। इसलिए (m+1=0) से (m=-1)।
