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
B. (3)
Concept
For degree (2), the coefficient of \(x^4\) must be (0). From (2d-6=0), (d=3).
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).
Exam Tip
डिग्री (2) के लिए \(x^4\) का गुणांक (0) होना चाहिए। (2d-6=0) से (d=3)।
