(5x-2-\(2x^2-3x\)+(4x-7)) को सरल करने पर (x) का गुणांक क्या होगा?
After simplifying (5x-2-\(2x^2-3x\)+(4x-7)), what is the coefficient of (x)?
Explanation opens after your attempt
C. (7)
Concept
The expression becomes \(5x^2-2x^2+3x+4x-7=3x^2+7x-7\). So the coefficient of (x) is (7).
Why this answer is correct
The correct answer is C. (7). The expression becomes \(5x^2-2x^2+3x+4x-7=3x^2+7x-7\). So the coefficient of (x) is (7).
Exam Tip
व्यंजक \(5x^2-2x^2+3x+4x-7=3x^2+7x-7\) बनेगा। इसलिए (x) का गुणांक (7) है।
