In problems PG 23 and PG 24 you found out how to change a quadratic function from the standard form
(standard form) y= ax^2+bx+c (graphing form) y=a(x-h)^2+k
which is to figure out the vertex by using the average of the x- intercepts and then to substitute it the coordinates of the vertex for h and k.
This is what Completing the Square method looks like.
Its similar to the box method that we used before but a bit different. Everything is pretty self explanatory because it works the same way.
