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