FACTORED POLYNOMIALS
The students will identify x-intercepts of polynomials and then write their own equations for polynomials.https://education.ti.com/en/activity/detail/factored-polynomials
Factoring Special Cases
Given a set of shapes whose combined areas represent the left-hand expression, students manipulate them to create rectangles whose areas are equal to the right-hand expression.https://education.ti.com/en/activity/detail/factoring-special-cases
