यदि (p(x)=(a-2)x-4+5x-2-3) में (a=2), तो (p(x)) की घात क्या होगी?

If (a=2) in (p(x)=(a-2)x-4+5x-2-3), what will be the degree of (p(x))?

Explanation opens after your attempt
Correct Answer

C. (2)

Step 1

Concept

At (a=2), the coefficient of \(x^4\) becomes (0). Therefore, the highest remaining power is (2).

Step 2

Why this answer is correct

The correct answer is C. (2). At (a=2), the coefficient of \(x^4\) becomes (0). Therefore, the highest remaining power is (2).

Step 3

Exam Tip

(a=2) पर \(x^4\) का गुणांक (0) हो जाता है। इसलिए सबसे बड़ी बची घात (2) है।
