In which polynomial is the coefficient of (x^5) equal to (0)?किस बहुपद में (x^5) का गुणांक (0) है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(3x^2+2x-4\)\(3x^2+2x-4\)
In \(3x^2+2x-4\), there is no \(x^5\) term, so the coefficient of \(x^5\) is \(0\). In contrast, the coefficient of \(x^5\) is \(1\) in \(x^5+1\), and it is \(2\) and \(9\) in \(2x^5-x\) and \(9x^5+7\), respectively. Exam tip: If a term of a required power is absent, its coefficient is \(0\).\(3x^2+2x-4\) में \(x^5\) वाला कोई पद नहीं है, इसलिए \(x^5\) का गुणांक \(0\) होता है। इसके विपरीत, \(x^5+1\) में \(x^5\) का गुणांक \(1\) है, जबकि \(2x^5-x\) और \(9x^5+7\) में यह क्रमशः \(2\) और \(9\) है। परीक्षा टिप: जिस घात का पद दिखाई न दे, उसका गुणांक \(0\) मानें।
