Solve Quadratics by Completing the Square

When there is no apparent way to factor a quadratic, you can use a technique called Completing the Square. This arranges the function in a form that allows you to factor and solve it. It's kinda complicated, some might even say hard. But it has to be learned so let's get started.

If a quadratic function is in this form, we can use a technique called 'completing the square'.
