Question

The function g(x) is a sum of squares.

Answer 1

•The function f(x) is a difference of squares. ---- y = x^2 -9
•The function g(x) is a sum of squares. ---- y = x^2 9
•The function h(x) is a perfect square trinomial. ---- y = x^2 6x 9
•The function j(x) can only have a GCF factored out of it. --- y = x^2 2x

1st y = (x 3)(x-3)
2nd is prime for real numbers
3rd y = (x 3)^2
4th y = x(x 2)
