Convert Quadratic Function to Vertex Form by Completing the Square

Your given a quadratic function in standard form, ax^2+bx+c, change it to vertex form by using a technique called completing the square.  Once in vertex form you can easily find the vertex of the function and its x intercepts.

If you have a negative in front of x^2 check out this video for an example.  Convert to vertex form with a negativ...
