Question

Please help me!!

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?

Answer 1

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

Answer 2

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

Answer 3

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