कौन-सा व्यंजक (x) में बहुपद है और उसका स्थिर पद (0) है?
Which expression is a polynomial in (x) and has constant term (0)?
Explanation opens after your attempt
A. \(x^3-4x\)
Concept
In \(x^3-4x\), there is no separate constant term, so the constant term is considered (0). Its powers are valid.
Why this answer is correct
The correct answer is A. \(x^3-4x\). In \(x^3-4x\), there is no separate constant term, so the constant term is considered (0). Its powers are valid.
Exam Tip
\(x^3-4x\) में कोई अलग स्थिर पद नहीं है, इसलिए स्थिर पद (0) माना जाता है। इसकी घातें मान्य हैं।
