व्यंजक (x-3\(x^2-5\)-x-5+9x-3) को सरल करने पर क्या मिलेगा?
What is obtained by simplifying (x-3\(x^2-5\)-x-5+9x-3)?
Explanation opens after your attempt
B. \(4x^3\)
Concept
(x-3\(x^2-5\)=x-5-5x-3), then \(-x^5\) cancels \(x^5\). The simplified form is \(4x^3\).
Why this answer is correct
The correct answer is B. \(4x^3\). (x-3\(x^2-5\)=x-5-5x-3), then \(-x^5\) cancels \(x^5\). The simplified form is \(4x^3\).
Exam Tip
(x-3\(x^2-5\)=x-5-5x-3), फिर \(-x^5\) से \(x^5\) कटता है। सरल रूप \(4x^3\) है।
