How do you simplify then factor the expression 12p - 8 + 6p + 14

Which statements are true for the functions g(x) = x2 and h(x) = –x2 ? check all that apply. for any value of x, g(x) will always be greater than h(x). for any value of x, h(x) will always be greater than g(x). g(x) > h(x) for x = -1. g(x) < h(x) for x = 3. for positive values of x, g(x) > h(x). for negative values of x, g(x) > h(x).
