At the 7:50 mark, the instructor forgot the "squared" on the 3x term, when finding f(-x).
In this lesson, we learn about zeros of a polynomial and various methods to find them. The fundamental theorem of algebra and linear factorization theorem are explained. We also learn about the rational root test, Carp's rule of science, and complex conjugates. These methods help us to determine the possible number of real and complex roots of a polynomial, which is essential in solving polynomials of higher degree. The use of graphing calculators and synthetic division is also discussed.
Overview of zeros of a polynomial
I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
