x^2 - 2x - 8
2 numbers that multiplied give -8
2 numbers that added give -2
2 x -4 = -8
2 + -4 = -2
(x + 2) (x -4 )
roots equal = -2, 4
x^2 - 2x -8
a. b. c because b is -2 in the equation you don't plug b as a negative
in the axis of symmetry
axis of symmetry = -b divide by 2a
2 divide by 2(1) =1
Vertex= (1, -9)
