(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

just the very beginning of the course, a simple problem, but I don't know how to write it in the "formal" way, so I need help with that.

2. Relevant equations

Need to prove that

A\(B\C) = (A\B)Ú(A∩C)

(forget about the little line in the Ú, just the only thing I found =\ )

3. The attempt at a solution

I see why this is true, I just have no idea how to write it formally
