Why this answer is correct
The correct answer is A. ((x-4)(x-1)(x+1)) / सही रूप. The grouping gives (x-2(x-4)-1(x-4)), and \(x^2-1\) factors. In exams look for both common bracket and difference of squares.
Exam Tip
समूह (x-2(x-4)-1(x-4)) बनता है और \(x^2-1\) टूटता है। परीक्षा में समान कोष्ठक और वर्गों का अंतर दोनों देखें।
