Algebra II Module 1, Topic D, Overview

high school student taking notes

Students extend their facility with solving polynomial equations to working with complex zeros.  Complex numbers are introduced via their relationship with geometric transformations.  The topic concludes with students realizing that every polynomial function can be written as a product of linear factors, which is not possible without complex numbers.
