यदि (p(x)=(2d-6)x-4+x-2+1) की डिग्री (2) है, तो (d) का मान क्या होगा?

If the degree of (p(x)=(2d-6)x-4+x-2+1) is (2), what is the value of (d)?

Explanation opens after your attempt
Correct Answer

B. (3)

Step 1

Concept

For degree (2), the coefficient of \(x^4\) must be (0). From (2d-6=0), (d=3).

Step 2

Why this answer is correct

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

Step 3

Exam Tip

डिग्री (2) के लिए \(x^4\) का गुणांक (0) होना चाहिए। (2d-6=0) से (d=3)।
