Learning Goals: Review how to solve quadratic equations and determine the number of roots.

Today I gave two handouts involving different methods of solving quadratic equations.  The following are three methods:

• Factoring
• Quadratic Formula
• Completing the square and isolating for x

Factoring is perhaps the quickest if the equation is factorable.  The quadratic formula will always work so use that when factoring is not possible.  Completing the square is similar to the quadratic formula and you are expected to be able to use this method upon demand.

Handout: Solving Quadratic Equations

Handout: The Discriminant

Here are some solutions and notes I gave in class.

Homework: 

Pg. 177 #1, 2, 4, 5

Pg. 185 #1-4, 6-10
