Writing an Equation in Vertex Form
In this lesson, you will learn how to transform an equation from standard form to vertex form by completing the square. The standard form is in the form of y equals a x squared plus b x plus c, while the vertex form is in the form of y equals a x minus h squared plus k. By factoring out the coefficient of x squared, completing the square, and simplifying, you can rewrite the equation in vertex form, which will give you the vertex, the compression or stretching factor, and the direction of opening.
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.
