व्यंजक (x-2\(x^2-3\)-x-4+2x) को सरल करने पर क्या मिलेगा?

What is obtained by simplifying (x-2\(x^2-3\)-x-4+2x)?

Explanation opens after your attempt
Correct Answer

B. \(-3x^2+2x\)

Step 1

Concept

(x-2\(x^2-3\)=x-4-3x-2), then \(-x^4\) cancels \(x^4\). The simplified form is \(-3x^2+2x\).

Step 2

Why this answer is correct

The correct answer is B. \(-3x^2+2x\). (x-2\(x^2-3\)=x-4-3x-2), then \(-x^4\) cancels \(x^4\). The simplified form is \(-3x^2+2x\).

Step 3

Exam Tip

(x-2\(x^2-3\)=x-4-3x-2), फिर \(-x^4\) से \(x^4\) कटता है। सरल रूप \(-3x^2+2x\) है।
