कौन सा व्यंजक (x) में बहुपद है लेकिन \(x^3\) का गुणांक (0) है?
Which expression is a polynomial in (x) but has coefficient of \(x^3\) equal to (0)?
Explanation opens after your attempt
A. \(2x^4-5x^2+1\)
Concept
\(2x^4-5x^2+1\) is a polynomial and the \(x^3\) term is absent. So the coefficient of \(x^3\) is (0).
Why this answer is correct
The correct answer is A. \(2x^4-5x^2+1\). \(2x^4-5x^2+1\) is a polynomial and the \(x^3\) term is absent. So the coefficient of \(x^3\) is (0).
Exam Tip
\(2x^4-5x^2+1\) बहुपद है और इसमें \(x^3\) पद अनुपस्थित है। इसलिए \(x^3\) का गुणांक (0) है।
