B. \(\frac{x+5}{x}\)

Step 1

Concept

\(\frac{x+5}{x}=1+\frac{5}{x}\) contains \(\frac{5}{x}\), whose power is (-1). So it is not a polynomial.

Step 2

Why this answer is correct

The correct answer is B. \(\frac{x+5}{x}\). \(\frac{x+5}{x}=1+\frac{5}{x}\) contains \(\frac{5}{x}\), whose power is (-1). So it is not a polynomial.

Step 3

Exam Tip

\(\frac{x+5}{x}=1+\frac{5}{x}\) में \(\frac{5}{x}\) की घात (-1) है। इसलिए यह बहुपद नहीं है।
