This video is an introduction to the rational root theorem. First, we define the rational root theorem, and then use one example to find ALL roots of a polynomial.

In this video, we graph a rational function by using the rational root theorem.

The video shows how to graph a 4th‑degree polynomial using its leading term, rational root theorem, and synthetic division:
