Question

Prove that (x+y') (x+z') = (x+y'+z) (x+y'+z) ( x+y+z) SOLUTION FOR THIS?

Answer 1

x'y'z + yz + xy = 
x'y'z + yz + xy(z + z') = 
x'y'z + yz + xyz + xyz' = 
(x'y' + y + xy)z + xyz' = 
(x'y' + y[x + x'] + xy)z + xyz' = 
(x'y' + xy + x'y + xy)z + xyz' = 
(x'[y'+y] + xy)z + xyz' = 
(x' + xy)z + xyz' = 
x'z + xyz + xyz' = 
x'z + xy(z +z') = 
x'z + xy
