If f(x) = 3x2 - 2x + 4 and g(x) = 5x + 6x - 8, find (f+g)(x).
A. (f+ g)(x) = -2x2 - 8x+ 12
B. (f+ g)(x) = 8x2 + 8x+12
C. (f+g)(x) = 8x2 + 4x - 4
D. (f+ g)(x) = 2x2 + 8x - 12

Kylie explained that (-4x+9)^2 will result in a difference of squares because (-4x+9)^2 (-4x+9)^2 =(-4x)^2+(9)^2=16x^2+81

Which of the following represents the zeros of f(x) = 6x3 − 31x2 + 4x + 5? −5, one third , one half 5, − one third , one half 5, one third , − one half 5, one third , one half
