व्यंजक (x-2(x+1)-x-3+4) को सरल करने पर कौन सा बहुपद मिलता है?

Which polynomial is obtained by simplifying (x-2(x+1)-x-3+4)?

Explanation opens after your attempt
Correct Answer

B. \(x^2+4\)

Step 1

Concept

(x-2(x+1)=x-3+x-2), then \(-x^3\) cancels \(x^3\). The simplified form is \(x^2+4\).

Step 2

Why this answer is correct

The correct answer is B. \(x^2+4\). (x-2(x+1)=x-3+x-2), then \(-x^3\) cancels \(x^3\). The simplified form is \(x^2+4\).

Step 3

Exam Tip

(x-2(x+1)=x-3+x-2), फिर \(-x^3\) से \(x^3\) कट जाता है। सरल रूप \(x^2+4\) है।
