Solve your equation and enter your answers below as a list of numbers, separated with a comma where necessary.

Answer 1

x^2 -12x +20

x^2 -12x + 36 +20 -36 (take half of -12, square it to get 36. Add & subtract 36)

(x-6)^2 - 16 The quadratic is now in vertex form, with vertex = (6,-16) = minimum point on the parabola
