यदि (p(x)=(a-3)x-6+2x-2-1) और (a=3), तो (p(x)) की डिग्री क्या है?

If (p(x)=(a-3)x-6+2x-2-1) and (a=3), what is the degree of (p(x))?

Explanation opens after your attempt
Correct Answer

C. (2)

Step 1

Concept

Putting (a=3) makes the coefficient of \(x^6\) equal to (0). The remaining highest power is (2).

Step 2

Why this answer is correct

The correct answer is C. (2). Putting (a=3) makes the coefficient of \(x^6\) equal to (0). The remaining highest power is (2).

Step 3

Exam Tip

(a=3) रखने पर \(x^6\) का गुणांक (0) हो जाता है। बची हुई सबसे बड़ी घात (2) है।
