In this Padlet, we will be exploring the way we add, subtract, multiply and divide rational expressions. But before we get into that, we need to know what rational expressions are and it's important components breaking it down.

There are two reliable ways to solve rational Expressions. Algebraically and Graphically.

A method in which you simplify the expression using the variables, polynomials, factoring, and canceling out. In the end, you will see the two exact answers which is definite to an answer to wondering if it’s equal or not.

# data[].attributes.body
A method in which you graph multiple points of two or more expressions on a graph. If they have the same x and y coordinates for the entirety of the graph, they are equal, if not they aren’t. This will not work all the time.

Well, we feel like it would make more sense to show you algebraically since it's more likely to get the answer right than graphically. It's more reliable.
