A quadratic equation is an equation of the form 2 ax bx c + + = , where a . Equations of this form can have two solutions, one solution or no solutions. Factoring The first method you can use is factoring. This method makes use of the Zero Product Property, that is, if ab = , then either a = 0 or b = 0. The equation must be written in the form 2 ax bx c + + = , so you may have to rewrite the equation in this form before you get started. Next youll factor the left hand side of the equation. Once in factored form, youll use the Zero Product Property to solve the equation.
