Lesson Plan: Factoring Trinomials Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to factor trinomials into a product of two binomials.

Objectives

Students will be able to

  • factor expressions that contain a common binomial factor into a product of two binomials,
  • fully factor simple quadratic and other single or two-variable trinomial expressions (whose leading terms have a coefficient of 1 or 1) into a product of two binomials,
  • fully factor quadratic and other single or two-variable trinomial expressions (whose leading terms have a coefficient greater than 1 or less than 1) into a product of two binomials,
  • solve geometric problems involving factoring trinomial expressions.

Prerequisites

Students should already be familiar with

  • factoring numerical expressions into products of factors,
  • factoring simple algebraic expressions by identifying the highest common factor of two or more terms.

Exclusions

Students will not cover

  • perfect square trinomials,
  • the difference of two squares,
  • polynomials with more than three terms.
