So I started with xy'+x'y+xz+y'z

I used a Kmap and ended up with the equvalent solution

z+x'y+xy'

From here I need to make this into a sum of two products and take the complement of it to get the solution I need.

But I see no way to turn this into a sum of two products

I can use the distributive law and end up with (z+x')(z+y)+xy'

But I'm pretty sure this is not sum of two products, at least not in the sense my book was showing me

Kmap:

xy\z 0 1
00   0 1   
01   1 1
11   0 1
10   1 1
