Explain in complete sentences the difference in the final product of these 2 polynomials: (a + b)^2 and (a - b)^2
Why does that difference occur?

anonymous · Answer

they  look identical to me
therefore the "difference" will be zero

anonymous · Answer

maybe there is a typo in the question, but there is no difference between $(a+b)^2$ and $(a+b)^2$ 
they are identical

oh, yeah, that was a typo, I meant to have the second equation as subraction, not addition. Oops..
