Find the dual of  ab + ab’ = a

Consensus xy + yz + x’z = xy + x’z Using consensus and other properties simplify to minimum SOP XY+X’YZ’+YZ

Find the dual of  a+(b+c)

Find the dual of  a’b’+a’b+ab+ab’=1

Simplify this expression to a minimum SOP (AB’+C’+DE’)(AB’+C’)

Simplify to minimum SOP A’B’+BC+AC+AB

Simplify this expression to a minimum SOP (AB’+C’+DE’)(AB’+C’)

Find the dual of  ab + ab’ = a

Simplify this to a minimum SOP AB'(C+D)+(C+D)’

Simplify this to a minimum SOP AB'(C+D)+(C+D)’
