निम्न में से कौन सा (x) में बहुपद है लेकिन (y) शामिल नहीं करता?
Which of the following is a polynomial in (x) and does not include (y)?
Explanation opens after your attempt
A. \(2x^2+3x-1\)
Concept
\(2x^2+3x-1\) has only (x) and valid powers. Therefore it is a polynomial in (x).
Why this answer is correct
The correct answer is A. \(2x^2+3x-1\). \(2x^2+3x-1\) has only (x) and valid powers. Therefore it is a polynomial in (x).
Exam Tip
\(2x^2+3x-1\) में केवल (x) है और घातें मान्य हैं। इसलिए यह (x) में बहुपद है।
