2.  1. Factoring  2. Quadratic Formula  3. Completing the Square 2

3. 3

4.  Remember, if the discriminant is a perfect square (like 4,9,16, or 25), then the roots are rational. If not, irrational. 4

5.  These formulas can save you lots of time on your Post-Test…and on the Regents Exam. Quadratic equation must be in this form: 5

6.  We had a Mini-lesson on December 22 nd on this topic…it is also on the school website, right next to this lesson. 6

7.  You need to be able to: 1. Solve a system of equations 2. Solve a higher-degree equation, like Pre-Test #7 3. Finally, there are 4 problems with Complex Fractions like #10 on Pre-Test. As always, there will be 4 on the Post-Test, too!!! ALWAYS CHECK YOUR ROOTS!!! Why? 7

8.  Research Artifact due TODAY!!! Place underneath Elmo when finished.  POST-TEST on Monday 8
