- 5.4: Real Zeros of Polynomials
- n this section, we will learn how to find good candidates to test using synthetic division. In the days before graphing technology was commonplace, mathematicians discovered a lot of clever tricks for determining the likely locations of zeros. Technology has provided a much simpler approach to narrow down potential candidates, but it is not always sufficient by itself.

- 5.5: Complex Zeros
- When finding the zeros of polynomials, at some point you’re faced with the problem x²=−1 . While there are clearly no real numbers that are solutions to this equation, leaving things there has a certain feel of incompleteness. To address that, we will need utilize the imaginary unit, i .
