The first step is to set the equation equal to zero, and see if it factors. If it factors, then factor completely, and set each factor equal to zero, forming two "mini-equations". Solve each the mini-equations. See my other Lesson Plan for this explanation.

IF THE EQUATION CANNOT BE FACTORED, then you will need to use the "Completing the Square Method" or the "Quadratic Formula." Here is the explanation you will need.
