In which polynomial is the coefficient of (x^3) equal to (0)?किस बहुपद में (x^3) का गुणांक (0) है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(4x^2+x+6\)\(4x^2+x+6\)
In \(4x^2+x+6\), there is no \(x^3\) term, so the coefficient of \(x^3\) is \(0\). In contrast, the coefficient of \(x^3\) is \(1\) in \(x^3+2\) and \(7x^3+1\), and \(2\) in \(2x^3-x\). Exam tip: If a term of a particular power is missing, its coefficient is taken as \(0\).\(4x^2+x+6\) में \(x^3\) वाला कोई पद नहीं है, इसलिए \(x^3\) का गुणांक \(0\) है। इसके विपरीत, \(x^3+2\) और \(7x^3+1\) में \(x^3\) का गुणांक \(1\) है, जबकि \(2x^3-x\) में यह \(2\) है। परीक्षा टिप: जिस घात का पद न दिया हो, उसका गुणांक हमेशा \(0\) माना जाता है।
