1) ABC' + AB' + AC + AB'C

here's what I got (don't laugh!)

= A(BC' + B' + C + B'C) - Factor out A

= A(B' + C' + B'C)

= A(B' + B'C')

= A(B' + C')

2) ABC'D + A'B'CD + A'BD + AC'D' + AB'C' + A'C'D

= ABC'D + A'B'CD + A'BD + AB'C' + C'

= A(BC'D + B'C') + A'(B'CD + BD) + C'

wellll I had no idea where to go from there....but I'm pretty sure what I got was wrong? Any help please....this is stressing me out.

Thankyou in Advance
