Lesson Summary:

In this lesson, you'll learn how to transfer an equation from standard form to vertex form. The first step is to factor out any coefficient that is not equal to 1, and then find b/2 squared. After this, you can add and subtract the value of b/2 squared to the equation to complete the square. Finally, use the completed square to write the equation in vertex form, and identify the vertex, compression, and direction of opening of the parabola.

Lesson Description:

Transfer an equation from standard form to vertex form

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.
