Problem Solving Using Quadratics

Students were given two problems to solve today, and were instructed to solve each problem 3 different ways. Using factoring, the quadratic formula, and graphing the equation are the ways I expect students to solve each problem. When done correctly, students should come up with the same answer for a particular problem.

Tonight's Homework: Complete both sides of the purple problem solving worksheet, and be sure each of the three ways is clearly expressed.
