Correct Answer

C. (m=3)

Step 1

Concept

For degree (4), the coefficient of \(x^6\) must be (0). From \(m^2-9=0\), \(m=\pm3\).

Step 2

Why this answer is correct

The correct answer is C. (m=3). For degree (4), the coefficient of \(x^6\) must be (0). From \(m^2-9=0\), \(m=\pm3\).

Step 3

Exam Tip

डिग्री (4) के लिए \(x^6\) का गुणांक (0) होना चाहिए। \(m^2-9=0\) से \(m=\pm3\) मिलता है।
