if $a'b+cd'=0$, then prove that $ab+c'(a'+d')=ab+bd+b'd'+a'c'd$

Let $a'b+cd'=0$, then prove that $$ab+c'(a'+d')=ab+bd+b'd'+a'c'd$$
I would like to know how to solve this expression, not able to make any headway. I have tried canonical form expansion and reduction but the terms in the if condition does not match and also not able to generate the terms in the given expression.

Hi! And welcome to MSE. I think that you are missing some relations. If you start considering $ab+c'(a'+d')$, you can not make appear $d$, since your unique relation $a'b+cd'=0$ does not contain any $d$, for example. Hence, I guess you have some missing relations. It could be between those $a,b,c,d$ and their respective $a',b',c',d'$. Let us know. Edit the post.
