I found this problem a little confusing on the class/home work today but, with some help, was able to figure it out.
4z^2+4zw+w^2 factored the problem looks like...
(2z+w)(2z+w) simplify to look like...
(2z+w)^2
I realize that this is not a difficult problem, but I thought the problem was not a perfect of squares.
