Synthetic Substitution and Remainder Theorem

The video tutorial from MooMooMath introduces synthetic substitution, also known as the remainder theorem, as a method to evaluate polynomials. It explains how to substitute values into a polynomial using function notation and synthetic division. The tutorial provides a step-by-step guide on performing synthetic division, highlighting the importance of the remainder in determining the output of a function. An example problem is solved to demonstrate the process, and the video concludes with a summary of the key points discussed.
