Rational Functions

Multiplication

To multiply two fractions you simply multiply the numerators and multiply the denominators:

a/b * c/d = (a*c)/(b*d).

Any common factors of the top and bottom can be cancelled first.

Example

(x*(x-3))/(x+1) * ((x+1)*(x-1))/(x*(x+2))=((x-3)*(x-1))/(x+2).  

More Examples (this will open in another window)

Exercise

Evaluate the multiplication and then check your answer.
