What is the coefficient of \(x^2\) in the polynomial \(p(x)=2x^4-5x^3+x-8\)?दिए गए बहुपद \(p(x)=2x^4-5x^3+x-8\) में \(x^2\) का गुणांक क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 00
The polynomial has no \(x^2\) term, so its coefficient is 0. The value \(-5\) is the coefficient of \(x^3\), while 1 is the coefficient of \(x\). Exam tip: if a power is missing from a polynomial, its coefficient is taken as 0.बहुपद में \(x^2\) पद उपस्थित नहीं है। ऐसे पद का गुणांक 0 माना जाता है, इसलिए सही उत्तर 0 है। विकल्प \(-5\) \(x^3\) का गुणांक और 1 \(x\) का गुणांक है। परीक्षा में किसी घात का पद न दिखे तो उसका गुणांक 0 लिखें।
