At this point in Algebra II our exploration of quadratics, students should be comfortable graphing and interpreting quadratic equations in multiple forms (standard, vertex, and intercept) as well as the process of completing the square. During week 15 we will complete our look at factoring and begin to solve quadratics by factoring and completing the square. Their are videos below that review previous topics as well as preview the upcoming factoring techniques we will cover in the coming week.

The homework for this week has already been given, but is included below as well. In addition, I have posted both the factoring decision tree as well as a cheat sheet that was compiled by Paul Dawkins for you use as reference sheets.
