• A=3x² , B=-8, C=5x

In order to graph a quadratic equation in standard form, the first two steps are to use the equation _____ to find the axis of symmetry (which is the x coordinate of the vertex), and then you can plug that value back into the equation to find the _____.

• -b/2a, y coordinate of the vertex

• (x-h)^2, y-intercept
  

• (x-r1), solution

• ax^2, vertex
