Response Details:
Whenever you divide something that is already in divison form you get the reciprocal of the second part and muliply it.
        Muliply
 Simplify
==     Cross out any common terms..
(you didnt need to solve the numerator for the "simplify" part but i wanted to show you that it doesnt make a difference
Hope that helped=)

Response Details:
((x2-y2)/(x-y))/((x+y)/(x2-y2)) =
 ((x2-y2)/(x-y))((x2-y2)/((x+y))=
(x2-y2)(x2-y2)/(x-y)(x+y)=
(x2-y2)(x2-y2)/(x2-y2) = (x2-y2)

Response Details:
since we are dividing take the second term and flip it over then multiply
 
 and we get
 
(x2-y2)2/(x+y)(x-y) this will simplify to
 
(x2-y2)2/(x2-y2) which can further simplify to
 
(x2-y2) we are done
 
Hope it helps
