__Unit Overview:__Students will perform algebraic operations on the complex number system, graph complex numbers, and solve quadratic equations with complex solutions. This unit culminates to proving that the Fundamental Theorem of Algebra extends to the complex number system.

__Enduring Understanding:__- The understandings and operations from the real numbers can be extended into the complex numbers.
- Every complex number can be broken into its real and imaginary part
- A quadratic equation can have real and imaginary solutions.

__Essential Question:__- Why do we use complex numbers?
- How are complex numbers an extension of the real number system?
