Convert the following equations into conjunctive normal form.
I tried to solve this question in 2 ways.
once with "Multiplying-out":

and also with "Shannon decomposition":
![](https://q2a.cs.uni-kl.de/?qa=blob&qa_blobid=10020913300313085085)
but each time I got a different answer and I don't know why. Would you please tell me what I did wrong in Shannon decomposition?
