Correct Answer
B. \(\frac{x^2+4}{x}\)
Concept
\(\frac{x^2+4}{x}=x+\frac{4}{x}\) contains \(\frac{4}{x}\), whose power is (-1). Hence it is not a polynomial.
Why this answer is correct
The correct answer is B. \(\frac{x^2+4}{x}\). \(\frac{x^2+4}{x}=x+\frac{4}{x}\) contains \(\frac{4}{x}\), whose power is (-1). Hence it is not a polynomial.
Exam Tip
\(\frac{x^2+4}{x}=x+\frac{4}{x}\) में \(\frac{4}{x}\) की घात (-1) है। इसलिए यह बहुपद नहीं है।
