factors are (x + 9)(x - 4) so x = 4 or -9. Does that help?
x2 + 5x - 120 can not be factored.
x2 + 5x + 6 = (x + 2)(x + 3)
The vertex is (-9, -62).
(x - 3)(x - 2)

x2 + 5x - 120 can not be factored.
x2 + 5x + 6 = (x + 2)(x + 3)
The vertex is (-9, -62).
2x + 5x = 7x
(x - 3)(x - 2)
The vertex of the positive parabola turns at point (-2, -11)
The vertex is at (-1,0).
x2 - 5x + 6 = (x - 2)(x - 3)
(3x - 5x) + (x2 - 6x2) = -2x -5x2 = -x(2 + 5x)
x2 + 5x + 3 = 9 x2 + 5x - 6 = 0 (x + 6)(x - 1) = 0 x = -6 or x = 1
x2+5x+6 = (x+2)(x+3)
