A. ((x-y-z)(x-y+z))सही रूप
Concept
First (x-2-2xy+y-2=(x-y)2), then apply difference of squares. In exams group first and apply the identity.
Why this answer is correct
The correct answer is A. ((x-y-z)(x-y+z)) / सही रूप. First (x-2-2xy+y-2=(x-y)2), then apply difference of squares. In exams group first and apply the identity.
