In which polynomial is the coefficient of (x^4) equal to (0)?किस बहुपद में (x^4) का गुणांक (0) है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(3x^2+x-6\)\(3x^2+x-6\)
In \(3x^2+x-6\), there is no \(x^4\) term, so the coefficient of \(x^4\) is \(0\). In contrast, the coefficients of \(x^4\) in \(x^4+2\), \(5x^4-x\), and \(7x^4+1\) are \(1\), \(5\), and \(7\), respectively. Exam tip: If a term of a particular power is absent in a polynomial, its coefficient is \(0\).\(3x^2+x-6\) में \(x^4\) का कोई पद नहीं है, इसलिए \(x^4\) का गुणांक \(0\) है। इसके विपरीत, \(x^4+2\), \(5x^4-x\) और \(7x^4+1\) में \(x^4\) के गुणांक क्रमशः \(1\), \(5\) और \(7\) हैं। परीक्षा टिप: जिस घात का पद बहुपद में न हो, उसका गुणांक \(0\) होता है।
