Which polynomial is a difference of two squares?
x2 − 16
x2 + 16
x2 − 8
x2 + 8
2 answers:
X2 - 16, is the answer. The first one.
x^2 - 16 = (x)^2 - 4^2, difference of two squares :)
The difference of two squares is of the form:
(a^2-b^2)
I believe that they might just want you to select
(x^2-16) which factors to (x-4)(x+4)
But there is nothing mathematically incorrect in doing the same for:
(x^2-8) which factors to (x-√8)(x+√8)
