What is the coefficient of (x) in ( (x-4)(x+6) )?( (x-4)(x+6) ) में (x) का गुणांक क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 22
\((x-4)(x+6)=x^2+6x-4x-24=x^2+2x-24\). Therefore, the coefficient of \(x\) is \(2\). The number \(-24\) is the constant term, not the coefficient of \(x\). Exam tip: simplify the expression by combining like terms before identifying a coefficient.\((x-4)(x+6)=x^2+6x-4x-24=x^2+2x-24\)। अतः \(x\) का गुणांक \(2\) है। \(-24\) स्थिर पद है, इसलिए वह \(x\) का गुणांक नहीं है। परीक्षा टिप: गुणांक ज्ञात करने के लिए पहले समान पदों को मिलाकर व्यंजक को सरल करें।
