यदि (p(x)=\(m^2-9\)x-6+5x-4-1) की डिग्री (4) है, तो (m) का संभावित मान कौन सा है?
If the degree of (p(x)=\(m^2-9\)x-6+5x-4-1) is (4), which can be a possible value of (m)?
Explanation opens after your attempt
C. (m=3)
Concept
For degree (4), the coefficient of \(x^6\) must be (0). From \(m^2-9=0\), \(m=\pm3\).
Why this answer is correct
The correct answer is C. (m=3). For degree (4), the coefficient of \(x^6\) must be (0). From \(m^2-9=0\), \(m=\pm3\).
Exam Tip
डिग्री (4) के लिए \(x^6\) का गुणांक (0) होना चाहिए। \(m^2-9=0\) से \(m=\pm3\) मिलता है।
