यदि (p(x)=2x-3+ax-2+5) में (a=0) हो, तो कौन-सा कथन सही है?

If (a=0) in (p(x)=2x-3+ax-2+5), which statement is correct?

Explanation opens after your attempt
Correct Answer

B. घात (3) रहेगीThe degree remains (3)

Step 1

Concept

When (a=0), the \(x^2\) term disappears but \(2x^3\) remains. Therefore, the degree stays (3).

Step 2

Why this answer is correct

The correct answer is B. घात (3) रहेगी / The degree remains (3). When (a=0), the \(x^2\) term disappears but \(2x^3\) remains. Therefore, the degree stays (3).

Step 3

Exam Tip

(a=0) पर \(x^2\) वाला पद हटता है लेकिन \(2x^3\) रहता है। इसलिए घात (3) ही रहेगी।
