In this lesson, the square root property is used to solve an equation. The first step is to isolate the variable by subtracting a number. Then, the square root of the remaining term is taken, but because it is a negative number, it is rewritten as i times the square root of the positive version of the number. The final answer is written in standard form as a plus bi, where a is the real number and bi is the imaginary number.
Solving an equation by using the square root property
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.
