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
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.
