Use Synthetic Division and NEVER Use Polynomial Long Division EVER again!

Struggling with polynomial long division? Well in this video I will explain how to use synthetic division to divide polynomials so that you never have to use polynomial long division EVER again!

Polynomial long division is a long, tedious, and difficult process that many of my students find confusing. Fortunately, the synthetic division process for dividing polynomials makes things fast, accurate, and fun!

In this video I will walk you through how to apply the synthetic division algorithm to divide a polynomial of degree 3 by a binomial of degree 1. Note that this example results in a remainder of zero.

There are many different ways to go about dividing polynomials. Be sure to learn both synthetic division and polynomial long division so that you can master the topic of polynomial functions!

What about dividing by x^2 + 2 or some other polynomial with degree >1

This doesn't work in all cases, does it? For instance, I tried dividing x^3 - 7x^2 - 2x + 6 by 2x + 2, and it only gives the correct answer in the long division method. I'm assuming this method would work as long as the coefficient of x of the divisor is 1?

I'll keep all the tools of the math-trade, thank you.
