Hi. I have this annoying problem that I can't seem to solve. It is:

Prove AD'+A'B+C'D+B'C = (A'+B'+C'+D')(A+B+C+D) using algebraic manipulation

My attempts have been fruitless. I combined the AD' + A'B terms, only to eliminate the A term. I did the same with C'D and B'C. I cannot see how to do with without eliminating one of the terms. Any help on this problem will be greatly appreciated!!! :D
