यदि (p(x)=\(m^2-4\)x-5+6x-3+1) की डिग्री (3) है, तो (m) का संभावित मान कौन सा है?

If the degree of (p(x)=\(m^2-4\)x-5+6x-3+1) is (3), which can be a possible value of (m)?

Explanation opens after your attempt
Correct Answer

B. (m=2)

Step 1

Concept

For degree (3), the coefficient of \(x^5\) must be (0). From \(m^2-4=0\), \(m=\pm2\).

Step 2

Why this answer is correct

The correct answer is B. (m=2). For degree (3), the coefficient of \(x^5\) must be (0). From \(m^2-4=0\), \(m=\pm2\).

Step 3

Exam Tip

डिग्री (3) के लिए \(x^5\) का गुणांक (0) होना चाहिए। \(m^2-4=0\) से \(m=\pm2\) मिलता है।
