In this factoring trinomials activity, high schoolers solve 5 multiple choice problems. Students factor trinomials using the box method or by separating the trinomial into the product of two binomials. High schoolers find the volume of a box by factoring a cubic with a GCF.
In this factoring trinomials instructional activity, students select the type of trinomial problem they wish to work on and click the interactive link. Each type of problem has thirty drills and practice problems linked to it. The problems themselves are not interactive.
Students use algebra tiles to identify the binomial factors and the graphing calculator to verify the result. In addition, they will identify the x-intercepts and y-intercepts of each trinomial function and explore relationships between the trinomial x2 + bx + c and its factored form (x + m)(x + n).
Here is a complete and clear demonstration of the process needed to factor a trinomial with a non-1 leading coefficient. Sal uses various colors and provides working examples while he factors the simple trinomial. This video would be perfect for those who are new to this concept.
Here is a practice problem used to demonstrate how to factor a trinomial with a leading coefficient. Sal completes the problem while explaining the patterns he sees, and how he uses those patterns to help him solve the problem. He also provides an alternative method to help students contextualize the factoring process. Great video, with a lot of number sense.
