The discriminant is a part of the quadratic formula, and can be a useful tool to explore the number and type of answers your equation will give.

(1) Move all terms to one side, and determine a, b, and c.
(2) Evaluate the discriminant.  
(3) if value is positive, you have 2 real solutions.  If value is negative, you have 2 complex solutions.  If value is 0, you have 1 real solution.
