यदि (p(x)=bx-4+3x-3-2x+1) और (b=0), तो (p(x)) की घात क्या होगी?

If (p(x)=bx-4+3x-3-2x+1) and (b=0), what will be the degree of (p(x))?

Correct Answer

C. (3)

Step 1

Concept

When (b=0), the \(x^4\) term disappears. Then the highest power remains (3).

Step 2

Why this answer is correct

The correct answer is C. (3). When (b=0), the \(x^4\) term disappears. Then the highest power remains (3).

Step 3

Exam Tip

(b=0) होने पर \(x^4\) वाला पद हट जाता है। तब सबसे बड़ी घात (3) रहती है।
