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
B. घात (3) रहेगीThe degree remains (3)
Concept
When (a=0), the \(x^2\) term disappears but \(2x^3\) remains. Therefore, the degree stays (3).
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).
Exam Tip
(a=0) पर \(x^2\) वाला पद हटता है लेकिन \(2x^3\) रहता है। इसलिए घात (3) ही रहेगी।
