Section 2: Solutions
Quadratics can be solved in a number of ways; some ways work better than others for different quadratic equations.
Have you ever seen a crime drama? There are specialists in blood splatter, firearms, special victims, etc. Just like in detective work, there are specialists in particular topics in mathematics.
Each member of your team will take on the role of "expert" in one or two different areas (#1-5) of solving quadratics equations. Investigate your method(s) by using the attached websites (and others!) and create a 3-4 slide Google Presentation summary of your method in your Drive and share it with your group members. If you have time, work on the problems in your section in the casebook. You will then share out your findings about your method(s).
Then, together as a group, complete each part and problem in your casebook as you look at your group member's presentations.
1. Graphing Method
2. Factoring Method
3. Square Root Method
4. Completing the Square Method
5. Quadratic Formula Method
6. Deciding on the Best Method
7. The Discriminant and the Nature of Roots
Section 3: Real World Applications
As we have already mentioned (and you have seen in the past), quadratics are everywhere. They are extremely useful in describing motion, modeling velocity of objects, and predicting patterns in data. The resources below will give you a detailed overview of the types of real world problems where quadratic modeling can be applied. Watch the example videos and then work with your partners to answer section 3 of your casebook.
