Lesson Summary:

In this lesson, you will learn how to find the value of x when two functions are set equal to each other. You will be shown how to set f(x) equal to g(x) and solve for x using algebra. By finding a set of linear factors, you can determine the possible values of x that make the equation true. This process is demonstrated step-by-step with an example problem, resulting in two possible solutions for x.

How to find the value of x when two functions are set equal to each other

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.

Questions answered by this video:
  • What is your next step after √(3x)+ 1= x + 1 ?
  • What is your next step after step:√(3x) = x ?
  • How would you find the values of x in x²- 3x = 0 ?
