Lesson Excerpt:

- "We are going to approach subtracting polynomials in the same way that we approached addition. Again, we are going to be looking for the like terms. You can only subtract the like terms, just as you can only add the like terms."

- "If the polynomials that you are going to be subtracting are written horizontally, then you will need to rewrite them so that they are written vertically. Once they are written vertically, you can go ahead and subtract the terms."
- "Let's start with an example."
