Correct Answer

A. ((x-y-z)(x-y+z))

Step 1

Concept

First (x-2-2xy+y-2=(x-y)2). In exams, then apply the difference of squares formula.

Step 2

Why this answer is correct

The correct answer is A. ((x-y-z)(x-y+z)). First (x-2-2xy+y-2=(x-y)2). In exams, then apply the difference of squares formula.

Step 3

Exam Tip

पहले (x-2-2xy+y-2=(x-y)2) बनता है। परीक्षा में फिर वर्गों के अंतर का सूत्र लगाएँ।
