व्यंजक (x-2\(x^3-4\)-x-5+7x-2) को सरल करने पर क्या मिलेगा?
What is obtained by simplifying (x-2\(x^3-4\)-x-5+7x-2)?
Explanation opens after your attempt
B. \(3x^2\)
Concept
(x-2\(x^3-4\)=x-5-4x-2), then \(-x^5\) cancels \(x^5\). The simplified form is \(3x^2\).
Why this answer is correct
The correct answer is B. \(3x^2\). (x-2\(x^3-4\)=x-5-4x-2), then \(-x^5\) cancels \(x^5\). The simplified form is \(3x^2\).
Exam Tip
(x-2\(x^3-4\)=x-5-4x-2), फिर \(-x^5\) से \(x^5\) कट जाता है। सरल रूप \(3x^2\) है।
