 What product results in x2 + 100?

 A. (x-10)2

B. (x2 + 10)

C. x(x - 100)

D. (x+10)(x-10)

 

 

 

 I really have no idea with this one. I think it is A but my teacher told me that was wrong but refused to explain why. Care to help me out?

It can't be any of these.

That's what I'm thinking now but the teacher specifically said "If you don't do all the problems, it is a 0." But this one is unsolvable, so what am I going to do? Hope he understands or make up some work and say I didn't understand it just to be safe?

Yeah, the only REMOTELY close one is D.

If your answer were: x^2 - 100, it would be "D". But, x^2 + 100, none of them!!.
