Correct Answer

B. \(x^4+\frac{2}{x}-1\)

Explanation

Simple Explanation

\(\frac{2}{x}=2x^{-1}\) है, जिसमें चर की घात ऋणात्मक है। एक अमान्य पद पूरे व्यंजक को बहुपद नहीं रहने देता। / \(\frac{2}{x}=2x^{-1}\), where the variable has a negative power. One invalid term prevents the whole expression from being a polynomial.
