कौन-सा व्यंजक (x) में बहुपद नहीं है लेकिन वास्तविक गुणांक रखता है?
Which expression is not a polynomial in (x) but has real coefficients?
Explanation opens after your attempt
Correct Answer
B. \(\frac{4}{x}-3\)
Concept
Having real coefficients is not enough. In \(\frac{4}{x}\), the power of (x) is (-1), so it is not a polynomial.
Why this answer is correct
The correct answer is B. \(\frac{4}{x}-3\). Having real coefficients is not enough. In \(\frac{4}{x}\), the power of (x) is (-1), so it is not a polynomial.
Exam Tip
वास्तविक गुणांक होना पर्याप्त नहीं है। \(\frac{4}{x}\) में (x) की घात (-1) है इसलिए यह बहुपद नहीं है।
