यदि (p(x)=2x-4+(a-5)x-2+3x-1) में (a=5), तो कौन-सा कथन सही है?
If (a=5) in (p(x)=2x-4+(a-5)x-2+3x-1), which statement is correct?
Explanation opens after your attempt
B. घात (4) रहेगीThe degree remains (4)
Concept
At (a=5), the \(x^2\) term disappears, but \(2x^4\) remains. Therefore, the degree remains (4).
Why this answer is correct
The correct answer is B. घात (4) रहेगी / The degree remains (4). At (a=5), the \(x^2\) term disappears, but \(2x^4\) remains. Therefore, the degree remains (4).
Exam Tip
(a=5) पर \(x^2\) पद हटता है, लेकिन \(2x^4\) मौजूद है। इसलिए घात (4) रहेगी।
