Lesson Purpose

The purpose of this lesson is for students to understand that the rules for factoring polynomials involve the simultaenous satisfaction of a very specific addition and multiplication calculation by using specific parts of the polynomial. This calculation is able to give the inverse result of a multiplication problem, and has direct application to may geometry questions. Finally, factoring a polynomial involves higher-order thinking skills that are helpful and analagous to the type of thinking required int he real world in order to solve complex problems involving more than one variable; particularly in the cases where recursive reasoning is necessary.

CCR Focus Standards

Algebra and Functions - Level E

• A.APR.1

  Understand that polynomials form a system analogous to the integers, namely, they are closed under the operations of addition, subtraction, and multiplication; add, subtract, and multiply polynomials. [NOTE: Emphasis should be on operations with polynomials.]

Supporting Standards

• A.CED.1

  Create equations and inequalities in one variable and use them to solve problems. Include equations arising from linear and quadratic functions, and simple rational and exponential functions.*
  

• A.APR.6

  Rewrite simple rational expressions in different forms; write a(x)/b(x) in the form q(x) + r(x)/b(x), where a(x), b(x), q(x), and r(x) are polynomials with the degree of r(x) less than the degree of b(x), using inspection, long division, or, for the more complicated examples, a computer algebra system.
