Homework Wednesday, 2/6

Pre-Algebra: Practice Test.  You must do at least 3 sections, or you can do several problems from each section.  Or more.  Answers below.  Test tomorrow.

Algebra: Pg. 182 #21 - 25 and pg. 186 #29 - 36.  Special Instructions: the problems as they are written only ask you to factor the trinomials.  What you need to do is change them so that they all become equations and set them equal to zero, then solve for x.
For example, if the problem asks you to factor the expression x^2 - 6x + 5, then you need to change it to the equation x^2 - 6x + 5 = 0, and then solve for x.
