Dividing Polynomials with Synthetic Division
The general form of synthetic division should read:
(ax^3 + bx^2 + cx + d) / (x + k).
Learn how to divide polynomials with synthetic division, a helpful shortcut to long division. This method works only when the polynomial is in the form of x minus k and then a x cubed plus b x squared plus c x plus t. Students will learn how to determine k and how to take the opposite of it. By taking the coefficients of the other polynomial, they will put them in the synthetic division area and then drop down the leading coefficients. They will then multiply k times the number and add vertically, continuing until there is a remainder.
How to divide polynomials using synthetic division
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.

Staff Review
All steps involved in setting up a synthetic division problem are shown. The problem is then completed by using synthetic division to find the quotient. Each of the resulting numbers is written as a coefficient of the resultant polynomial including the remainder.
