Week 14/ Multiplying and Dividing Rational Expressions

When multiplying and dividing rational expressions the steps you want to take are:

Step 1: Check if their are no plus or minus symboles, (this means that if their are no plus or minus symboles you can cancel out terms on the top and bottom)

Step 2: Factor both the numerator and the denominator on the fraction

Step 3: Write the non-permissible values x cannot equal (number) (To find the non-permissible values its what ever is in the denomonator that is after factored form.) Ex. $latex \frac{(-x+1)}{(x-1)} the Non-permissible values are x cannot equal 1, because you cannot have a 0 as your denominator.

Step 4: Simplify the rational exspression

Step 5: Cancel out any of the same simplified exspressions. (Note, if the number is \frac{(-x+1)}{(x-1)} you can take a -1 out of the (-x+1) and make it the same as (x-1) then cancel them out leaving you with -1.)

Step 6: leave it in factored form
