Solving Quadratic Equations by Factoring

ZERO- FACTOR PRINCIPLE :

 if and only if

Solving quadratic equations by factoring:

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, .
