Multiplying rational expressions | Precalculus | Khan Academy

When we multiply rational expressions, we multiply both numerators and multiply both denominators. We can also see if we can reduce the product to lowest terms. This is very similar to multiplying fractions, only we also have to think about the domain while we do it.

what does "Domain" mean?

[@tallspartan117]

Its all possible values from left to right on a graph. Range is all the possible values up and down. (x,y) The domain is the X and the Y is the range. You might have seen them written like this (-∞, ∞) that just means that the graph goes infinity both directions.
