Boolean algebra help?

Question

I started with AC + A'BD' + A'BE + A'C'DE
I got to AC + A'(BD' + BE + C'DE)
Then to (A + BD' + BE + C'DE)(A' + C)
Then to (A + C'DE + B(D' + E)) (A' + C)
Then to (A + B + C'DE)(A + C'DE + D' + E)(A' + C)

What can I do from here?

Answer 1

i think that this line is not correct :

(A + BD' + BE + C'DE)(A' + C)

you are introducing an extra term CBD'
