What is the coefficient of (x) in the expression (9-5x)?व्यंजक (9-5x) में (x) का गुणांक क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(-5\)\(-5\)
In \(9-5x\), the term containing \(x\) is \(-5x\). The number multiplying \(x\) is \(-5\), so the coefficient of \(x\) is \(-5\). Choosing \(5\) would ignore the negative sign. Exam tip: always include the sign of the term while identifying a coefficient.व्यंजक \(9-5x\) में \(x\) वाला पद \(-5x\) है। \(x\) के साथ गुणा होने वाली संख्या \(-5\) है, इसलिए \(x\) का गुणांक \(-5\) है। \(5\) चुनने पर ऋण चिह्न छूट जाएगा। परीक्षा में पद के साथ लगे चिह्न को हमेशा गुणांक का भाग मानें।
