In this lesson, you will learn how to solve a quadratic equation when a=2 using three different methods. The first method involves factoring out what the two binomials have in common. The second method involves writing the two binomials as the two terms in the equation and factoring by grouping. The third method involves representing the equation as an area and finding the factors. By the end of the lesson, you will have the skills to solve quadratic equations with ease.
How to solve a quadratic equation when a=2
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.
