Answer 1

we have
\[ (x+y)/(x-y)+ 1/(x+y)-(x^2+y^2)/(x^2-y^2)\]
take LCM of (x+y) (x-y) and (x^2-y^2) it comes out to be (x^2-y^2)
\[ ((x+y)^2+(x-y)-(x^2+y^2))/(x^2-y^2)\]
we get \[ (x-y-2xy)/(x^2-y^2)\]

Answer 2

zed can uhelp me

Answer 3

open the braces some if them will cutted and then open braces of (x^2-y^2)as (x-y)(x+y)

Answer 4

i hope after this it will be proved
