how about rewriting (A U B) ∩ (A U C) as (A∩A) U (B ∩ C) ? I mean that what it LHS implies... right? I mean that's what gonna happen if u calculate that... rest will fall out. 🙂

When proving that the set identity

A union (B intersect C) = (A union B) intersect (A union C)

is true, is it sufficient to "go from the LHS to the RHS" instead of "going from the LHS to the RHS and back to the LHS" as shown in the video?
