A: Sometimes

B: Always

C: Never 

*is it a?

anonymous · Answer

I think it is B because it would end up being a^2-ab-ba+b^2 Unless there is a zero of course so then it could be A

The product of (a-b)(a-b) is a^2-2ab+b^2 now what conclusion do you think.

Find the two products below. Compare and contrast, in complete sentences, the similarities and differences of the two.

(x + 4)(x − 4) and (x + 4)(x + 4)

anonymous · Answer

the first would play out to x^2-4x+4x-16 leaving you with x^2-16
The second would become x^2+4x+4x+14 leaving you with x^2+8x+14
See the difference?

anonymous · Answer

So the second is +16 not +14
