  • Find x intercepts of y= -(x+2)(x+7)
    -2, -7
  • Find the axis of symmetry of the equation y=(x+5)(x-3)
    x=1
  • What form is this written in? y=-3(x-1)(x+2)
    Intercept form
  • Is this equation reflected? y=2(x-8)(x-100)
    No
  • Factor the equation to find the zeros. y=x^2-16x+64
    Factors to (x-8)(x-8) or (x-8)^2 so the zero is at 8
  • Find x intercepts of y=(x+3)(x-11)
    -3, 11
  • Find x intercepts of y= 2(x-9)(x-6)
    9, 6
  • What form is this written in? y= 6(x+2)^2+8
    Vertex Form
  • What form is this written in? y=5(x+1)(x-2)
    Intercept Form
  • Is this equation reflected? y=-12(x+3)(x-93)
    yes
  • Factor to find the zeros. y=x^2+3x+2
    Factors to (x+1)(x+2) so, -1 and -2
  • Find the axis of symmetry of the equation y=(x-1)(x-7)
    x=-4
  • Factor to find the zeros. y=x^2+10x+21
    Factors to (x+7)(x+3) so zeros are -7 and -3
  • Factor the equation to find the zeros. y=x^2-2x-8
    Factors to (x-4)(x+2) so zeros are 4 and -2
  • Find the axis of symmetry of the equation. y=(x+1)(x-3)
    x=-1
  • Find x intercepts of y=x(x+1)
    0, -1
  • Find the axis of symmetry of the equation y=(x-2)(x+2)
    x=0
