Select the two polynomials that have a product of n2 – 1.

Question

Select the two polynomials that have a product of n² – 1.

The products I got were: n^2 - 1 and n^2 +1



Answer 1

n² – 1

(n - 1)(n + 1) = n^2 -1

If you multiply your answers together, you do not get n² – 1



Answer 2

n² - 1 =(n + 1)(n - 1)
