Algebra 1: Factoring Trinomials Part 1
by Texas Instruments

Published on October 10, 2012

Objectives

  • Factor trinomials of the form x2 + bx + c, where b and c are positive integers
  • Relate factoring a quadratic trinomial to an area model
  • Generalize the process for factoring trinomials of the form x2 + bx + c, where b and c are positive integers

Vocabulary

  • trinomials
  • factor

About the Lesson

This lesson involves factoring trinomials using a dynamic area model. As such, it is implicit that x represents a positive quantity. As a result, students will factor trinomials of the form x2 + bx + c, where b and c are positive integers, recognizing that in general the factors of c that sum to b are those needed to correctly factor the trinomial.
