Lesson Summary:

In this lesson, you will learn how to find the polynomial when given imaginary zeros. To do this, you first need to understand conjugate pairs and how they relate to complex zeros. Once you have identified the zeros, you can find the factors and then use a box method to multiply them out and simplify the result to find the polynomial. This lesson includes helpful tips and visuals to make the process easier to understand.

Lesson Description:

Finding the polynomial when given imaginary zeros

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.
