Question

A/ab-bsquare + b/ab-asquare?​

Answer 1

`((a+b))/(ab)`

Explanation:

The given expression is :

`(a)/(ab-b^2)+(b)/(ab-a^2)`

It can be solved as follows :

`(a)/(ab-b^2)+(b)/(ab-a^2)=(a)/(b(a-b))+(b)/(a(b-a))\\\\=(a)/(b(a-b))+(b)/(-a(-b+a))\\\\=(1)/(a-b)((a)/(b)-(b)/(a))\\\\=(a^2-b^2)/(ab(a-b))\\\\=((a-b)(a+b))/(ab(a-b))\\\\=((a+b))/(ab)`

So, the solution of the given expression is equal to
`((a+b))/(ab)`.
