कौन-सा व्यंजक (x) में बहुपद नहीं है क्योंकि उसमें (x) हर में है?
Which expression is not a polynomial in (x) because it has (x) in the denominator?
Explanation opens after your attempt
C. \(\frac{x^2+1}{x}\)
Concept
\(\frac{x^2+1}{x}=x+\frac{1}{x}\) contains \(\frac{1}{x}\), whose power is (-1). Therefore, it is not a polynomial.
Why this answer is correct
The correct answer is C. \(\frac{x^2+1}{x}\). \(\frac{x^2+1}{x}=x+\frac{1}{x}\) contains \(\frac{1}{x}\), whose power is (-1). Therefore, it is not a polynomial.
Exam Tip
\(\frac{x^2+1}{x}=x+\frac{1}{x}\) में \(\frac{1}{x}\) की घात (-1) है। इसलिए यह बहुपद नहीं है।
