Going through my review material, and I need some help on this simple procedure.
example 1: (2x + 1)^2
example 2: 2(x^2 -1)
I forgot how to do this. Can someone please help me out?
The Attempt at a Solution
Example 1: 2x squared is 4x?... I dunno. I am stuck. I need a good review on how to do this simple procedure. Any website link to a review/refreasher would be good.
