Homework Statement
Convert f=(x'+y)(x+z)(y+z) from product of sums form, into the canonical product of sums.
Homework Equations
boolean logic, et al.
The Attempt at a Solution
This is boolean logic (so + is "or" and * is "and" etc..)
There has to be some stupidly simple thing I am overlooking here. I chose to break it down and work each Maxterm by itself.
So the first thing to expand is:
(x'+y)
and so:
(x'+y) = x' + y + zz' since zz' = 0 this is okay.
Now here is the part I am not following.
I know that x' + y + zz' = (x' + y + z)(x' + y + z')
but I don't know how this expansion is happening.
