In this lesson, we learn how to multiply complex numbers that involve radicals and imaginary numbers. The first step is to factor out the negative and treat it as an imaginary number. We then simplify the radicals and multiply the numbers and i's. Remembering that i squared is equal to negative one, we arrive at our final answer. This lesson is a great tool for those who want to learn how to simplify and multiply with imaginary numbers in a clear and concise manner.

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.
