__Quadratic Formula by Jenn__


x = __0 ± √02 – 4(1)(-9)__ 2(1)

x = __0 ± √0 + 36__ 2

x = __0 ± √36__ 2

x = __0 ± 6__ 2

x = __0 + 6__ 2 **x = 3 **

x = __0 - 6__ 2 **x = -3

__Vertex/Axis by Mat__
 Vertex/Axis by Mat vertex= (0,-1) 0=axis of symmetry

__Completing the Square by Michelle__
 Equation: x^2 + 0x - 9 x-intercepts: (3,0) (-3,0) 0=x^2 + 0x - 9 +9 = x^2  **√9 = √x^2 **  ± 3 = x (3,0) (-3,0)

__Factoring by Michelle__
 (-3,0) (3,0) (x+3) (x-3) x^2 - 3x + 3x - 9 x^2 - 0 - 9
 * x^2 - 9 **
