# Solving Quadratic Equations by Factoring

ZERO- FACTOR PRINCIPLE : if and only if 1. Write the equation in form.
2. Factor the nonzero side of the equation.
3. Use the zero -factor principle to set each factor equal to zero .
4. Solve each resulting linear equation.

The Quadratic Formula : The solutions of the equation are The Discriminant is (the expression underneath the radical sign ).

Let D represent the Discriminant. In other words, . number and type of solutions number of x - intercept points two complex (conjugate) solutions none exactly one real solution exactly one ( it is the vertex ) exactly two distinct real solutions exactly two
