Given Equation is a^2 - x^2 - 2xy - y^2
= > a^2 + ax - ax - x^2 - xy - xy + ay - ay - y^2
= > a^2 + ax + ay - ax - x^2 - xy - ay - xy - y^2
= > a(a + x + y) - x(a + x + y) - y(a + x + y)
= > (a - x - y)(a + x + y).
Hope it helps!

i don't understand what you have done
just added xy and subtracted xy
Can you put a bracket and change the sign of the expression which is in the bracket ? jUst a question

a२-(X2+2xy+Y2)
or,(a)2-(X+Y)2
or, (a+X+Y) (A-X-Y) ans
or,(a)2-(X+Y)2
or, (a+X+Y) (A-X-Y) ans
Wait, you can put a bracket and change the sign of the expression which is in the bracket ?
