Completing the Square: Deriving the Vertex Formula

purplemath.com/modules/sqrvertx2.htm

Practically speaking, you can just memorize that h = –b / (2a) and then plug your value for "h" back in to "y =" to calculate "k".If you're allowed to use this formula, you can then more quickly find the vertex, because simply calculating h = –b / (2a) and then finding k is a lot faster than completing the square.
