In this lesson, we will discuss complex roots of polynomial equations. Specifically, we want to understand what a complex root physically means. Complex roots arise when the quadratic has no crossing points along the x-axis.

We discuss the idea that all functions can take as inputs complex numbers, so the complex roots are just those values that drive the function to zero in the complex plane.
