You teach!
• To quickly review the different types of factoring, each group will get an equations and give a BRIEF explanation of how to factor.
• I will RANDOMLY choose two
members to come up and teach---so EVERYONE in your group should be prepared!

The number of cars sold in 1990 can be
modeled by the expression 2x3 + 7x - 5. In 2010, the number of cars sold can be
modeled by the expression 4x3 - 3.
Write an expression that modeled how many more cars were sold in 2010 than in
1990.
