SOLVING QUADRATIC EQUATIONS

Note:

• A quadratic equation is a polynomial equation of degree 2.

• The "U" shaped graph of a quadratic is called a parabola.

• A quadratic equation has two solutions. Either two distinct real solutions, one double real solution or two imaginary solutions.

• The are several methods you can use to solve a quadratic equation:
  1. Factoring

  2. Completing the Square

  3. Quadratic Formula

  4. Graphing

• All methods start with setting the equation equal to zero.
