Okay.. I'm taking a college CLEP test on Thursday. I've been studying for a while. But, I have one question I can't figure out. I know its easy,
but since I'm out of school my mind is shut off. I was wondering if anyone could help me understand it.
The question is Which of this following is a factor of 4 - (x+y)^2
A.) - (x+y)^2
B.) x+y
C.) 2 - x+y
D.) 2+x+y
E.) 4+x+y
I know the answer is D, but I've tried almost everyway and I can't seem to crasps how they got it. I was wondering if anyone could explain this to
me. Thanks,
Alias
