**drwls**, Tuesday, March 18, 2008 at 1:45amTry simplifying

x^2+2x-3/x^2-9 to (x+3)(x-1)/[(x+3)(x-3)]

= (x-1)/(x-3)

Similarly factor what you can in the x^2-1/x^3-27

and you will get some more cancellations when you do the final division.

Hint: x^3-27 can be factored, and one of its factors is (x-3). I wil leave you to figure out the other one.
