To begin Unit 9 in the Common Core Algebra I series, scholars view a video presentation on determining the greatest common factor for algebraic expressions. They see how to use factoring and the zero product property to solve polynomial equations. Another lesson focuses on factoring second-degree trinomials. Viewers also learn about the magic X method to keep track of the constant factors. The third lesson shows a technique to factor trinomials when the leading coefficient is not one. The series continues with pupils viewing a video presentation that shows how to combine all the factoring techniques from Unit 9 to factor in more complex polynomials. The unit review asks pupils to work through 16 problems to review factoring. The problems consist of straight factoring polynomial expressions, solving equations by factoring, and applying factoring to real-world problems.
