Setting up a K-map for (x+y)(x+y')

[Heat]

Homework Statement

I understand the basic of kmaps like
xy+xy' =
y y'
x 1 1
x' 0 0

would be x.

but when we have (x+y)(x+y'), how would that be setup?

The easiest way is change the product of sums to a sum of products by "multiplying it out" using the properties of and, or, and complement and simplifying. Alternatively you can evaluate the expression for the four possibilities (x,y) = (0,0) or (0,1) or (1,0) or (1,1) in fill in the K- table with the results.
