Tuesday 11/3, we will have our main test for Chapter 2. It will cover sections 2.1, 2.3-2.6, 2.8 (part), and extra material that we covered during this unit (such as GCF and LCM).

Your only homework this weekend is to prepare for the test. Monday we will start rational functions (section 2.7) but that topic will not be on the test.
