किस विकल्प में बहुपद की डिग्री (3) है लेकिन \(x^2\) का गुणांक (0) है?
Which option has degree (3) but the coefficient of \(x^2\) is (0)?
Explanation opens after your attempt
A. \(2x^3+5x-1\)
Concept
In \(2x^3+5x-1\), the highest power is (3) and the \(x^2\) term is absent. So the coefficient of \(x^2\) is (0).
Why this answer is correct
The correct answer is A. \(2x^3+5x-1\). In \(2x^3+5x-1\), the highest power is (3) and the \(x^2\) term is absent. So the coefficient of \(x^2\) is (0).
Exam Tip
\(2x^3+5x-1\) में सबसे बड़ी घात (3) है और \(x^2\) पद नहीं है। इसलिए \(x^2\) का गुणांक (0) है।
