What do you think a rational expression is?

Consider the word: rational - what is it made of?

Consider: what is an expression?

I can multiply and divide rational expressions.

how do you multiply rational expressions (fractions)?

1. Multiply straight across (multiply the numerators, multiply the denominators)

2. Cancel what you can

how do you divide rational expressions (fractions)?

1. Multiply the first one by the reciprocal of the second one (flip the second fraction upside down)

2. Cancel what you can

Let's do some examples!

STEPS:

1. Factor everything as much as possible

2. Multiply or divide

3. Cancel what you can (you can also cancel before you multiply or divide if you want)

4. Only cancel things that are multiplied or divided! You cannot cancel things that are added or subtracted.

Let's start our work together. Work on your own when you're ready!
