How would you solve the problem
(w - 2)^2
So far I've gotten w^2-2w*2-4
Where do I go from here?
Have I even gotten what I have right?
I understand when I'm with my teacher, but as soon as I got home, I was a little lost. So any help would be great!!
You are almost there
your first line in the expansion probably was
w^2 - 2w - 2w + 4
the only terms we can add up are the two 2w terms
= w^2 - 4w + 4
