Methods for solving quadratic equations including factoring, completing the square, and the quadratic formula.

Vertex Equation

y = (x - 0.0)^2 + 0.0

Scale factor (a)1.0

Horizontal shift (h)0.0

Vertical shift (k)0.0

Expanded Standard Form

y = 1.0x^2 + 0.0x + 0.0

Formula:

y = ax^2 - 2ahx + (ah^2 + k)
