Answer 1

Answer:

x-y/x+y

Step-by-step explanation:

{x/(x-y)} - {y/(x+y)} - 2xy/(x^2 -y^2)

= [{x(x+y) - y(x-y)} / (x^2 -y^2)] - 2xy/(x^2 -y^2)

=[(x^2 +xy -xy + y^2) / (x^2 -y^2)] - 2xy/(x^2 -y^2)

=[(x^2 + y^2) / (x^2 -y^2)] - 2xy/(x^2 -y^2)

=(x^2 + y^2 - 2xy) / (x^2 -y^2)

= (x-y)^2 / (x^2 -y^2)

= (x-y)^2 / (x+y)(x-y)

= (x-y)/(x+y)

is that okay?
