Lesson Summary:

In this lesson, you will learn how to transfer an equation from standard form to vertex form when b is not divisible by 2. The first step is to get the form x squared plus vx by putting parentheses around the x term and separating it from the constant term. Then, you need to complete the square by finding the value of v over 2 squared. After that, add and subtract the resulting value on both sides to rewrite the equation as a perfect square. Simplify the equation and voila, you now have it in vertex form. Even if you end up with fractions, just make sure to follow the rules of adding and subtracting fractions.

Lesson Description:

Transfer an equation from standard form to vertex form when b is not divisible

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.
