Step-by-step directions help young mathematicians learn how to factor using two strategies. With the written steps on the right and the algebra steps on the left, learners are sure to understand how the problem goes from an expression to...

Use division and factoring to determine the leading 1 coefficient. This presentation thoroughly explains how to factor a trinomial in order to determine its common factors.

Factoring is one of the first places in math that a young algebrist runs into multiple ways to work a problem. For the more concrete learner who needs a visual structure for problem solving, this presentation of factoring using a Punnett...

Take your class through the mechanics of simplifying algebraic fractions by factoring trinomials. Though the steps for factoring are assumed known, the process of identifying and canceling common factors are detailed with care and...

Explore the puzzle of factoring quadratic trinomials using the video lesson. The instructor demonstrates the trial and error process of finding the binomial factors. She shows how to check the factors using multiplication.

Have the class factor and solve trinomials of integers in the form x2 + bx + c, where b and c are positive. They relate factoring to area and then follow a specific format to factor their trinomials. Tiles are used to help them relate...
