Which expression is not a polynomial in (x) but has real coefficients?कौन-सा व्यंजक (x) में बहुपद नहीं है लेकिन वास्तविक गुणांक रखता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\frac{4}{x}-3)(\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.वास्तविक गुणांक होना पर्याप्त नहीं है। (\frac{4}{x}) में (x) की घात (-1) है इसलिए यह बहुपद नहीं है।
