## Part 1

In the first video, we are going to add and subtract simple rational expressions.

**For example:**

Simply combine the numerator and the denominator together if the denominators are the same and we have

**Let’s look at another example:**

Since the denominators are not the same, multiple each fraction to achieve the least common multiple

Now, we can add the terms together

In order to reduce the expression, factor if necessary

Reduce, and our final answer is

## Part 2

In the second video, we are going to add and subtract more complex rational expressions.

**For example:**

Multiply each fraction to achieve the least common multiple

Use the distributive property to multiply

Now that we have common denominators, add the numerators together

Factor any expression if necessary

Since nothing can be reduced, we are going back to the original expression

Use FOIL (First, Outside, Inside, Last) to multiply

Combine like terms, and we have
