What is the rational zero test?

The video tutorial explains the rational zero test, its importance, and historical context. It defines a polynomial and details the rational zero test, which identifies possible rational zeros of a polynomial in the form P/Q. An example is provided to illustrate the application of the test, showing how to determine potential rational zeros. The tutorial concludes with a discussion on the practical use of the test in verifying solutions and graphing.
