Algebra 2: Synthetic Division and Factoring Polynomials

Hey there math friends! In this post we will go over how and when to use synthetic division to factor polynomials! So far, in algebra we have gotten used to factoring polynomials with variables raised to the second power, but this post explores how to factor polynomials with variables raised to the third degree and beyond!

If you have any questions don’t hesitate to comment or check out the video below. Also, don’t forget to master your skills with the practice questions at the end of this post. Happy calculating! 🙂

What is Synthetic Division?

Synthetic Division is a shortcut that allows us to easily divide polynomials as opposed to using the long division method.

When can we use Synthetic Division?

We can only use synthetic division when we divide a polynomial by a binomial in the form of (x-c), where c is a constant number.

Check out the Example below to see synthetic division in action:

Synthetic Division can also be used when Factoring Polynomials!

Let’s take a look at the following example and use synthetic division to factor the given polynomial:
