You may want to review dividing exponentials and multiplying polynomials by monomials first.

Dividing polynomials by monomials is much like multiplying them.
Now, however, you need to *divide* each term of the
polynomial by the monomial. For example, suppose you want to
divide (2*x*^{2} − 6*x*)/(2*x*). Then
the answer is 2*x*^{2}/(2*x*) −
6*x*/(2*x*), or *x* − 3.
