I'm having trouble finding the 2 numbers to start with

OpenStudy (ashleyisakitty):

Well, i dont think you need to simplfy, so scratch that. Lets start be reordering the terms! Do you know how to do that? Its okay if you dont :)

OpenStudy (tkhunny):

It's going to look like this: (x __ ____)(x __ ____) Since the constant term is positive, it must be one of these (x + ____)(x + ____) or (x - ____)(x - ____) You're almost done!
