व्यंजक (x-3(x-2)-x-4+6x) को सरल करने पर कौन सा बहुपद मिलता है?

Which polynomial is obtained by simplifying (x-3(x-2)-x-4+6x)?

Explanation opens after your attempt
Correct Answer

B. \(-2x^3+6x\)

Step 1

Concept

(x-3(x-2)=x-4-2x-3), then \(-x^4\) cancels \(x^4\). The simplified form is \(-2x^3+6x\).

Step 2

Why this answer is correct

The correct answer is B. \(-2x^3+6x\). (x-3(x-2)=x-4-2x-3), then \(-x^4\) cancels \(x^4\). The simplified form is \(-2x^3+6x\).

Step 3

Exam Tip

(x-3(x-2)=x-4-2x-3), फिर \(-x^4\) से \(x^4\) कट जाता है। सरल रूप \(-2x^3+6x\) है।
