The file contains two different resources. There are guided notes that show how to find the discriminant and what the answer tells you about the type of solutions. There is also then practice on solving using the quadratic formula. Complex numbers are in some of the solutions.
There is also a homework assignment (with answers) included to follow up with this lesson as well.
This lesson is part of a unit for sale in my store if you are interested in the entire curriculum for Quadratics.
