[University Math] Intro to proofs course, set theory and the cartesian product

The question is

Is it true that (AxA)(BxB) = (A\B)x(A\B) for any two sets A,B? If it is true, prove it. Otherwise, find a counterexample.

I've done some rough work with two examples and based off these two it seems like this identity is true, and so now I'll have to try and prove it.

I was just posting to make sure my understanding of AxA is correct since the cartesian production of a single set is not something that is mentioned in the course notes.

Also does anyone have any idea on how I can go about starting this proof, if there is one?
