\(x^3+x^2-x-1\) को समूहीकरण से गुणनखंडित करें।
Factorise \(x^3+x^2-x-1\) by grouping.
Explanation opens after your attempt
Correct Answer
A. ((x+1)2(x-1))सही रूप
Concept
The grouping gives (x-2(x+1)-1(x+1)), then \(x^2-1\) also factors. In exams check again after partial factorisation.
Why this answer is correct
The correct answer is A. ((x+1)2(x-1)) / सही रूप. The grouping gives (x-2(x+1)-1(x+1)), then \(x^2-1\) also factors. In exams check again after partial factorisation.
Exam Tip
समूह (x-2(x+1)-1(x+1)) बनता है, फिर \(x^2-1\) भी टूटता है। परीक्षा में आंशिक गुणनखंड के बाद फिर जांचें।
