I am having trouble with this.
Add (simplify if possible)
(x^2 + 11x)/(x^2  3x) + (x^2  6x)/(x^2  3x)
I actully came up with two possible answers.
(2x+5)/x3 and (2x^25)/x6x
I'm not sure which answer is correct.

The denominators of the two added terms can be written x(x3). The x^26x term can be written x(x6). Therefore
(x^2 + 11x)/(x^2  3x) + (x^2  6x)/(x^2  3x) = [x(x+11) + x(x6)]/[(x(x3)]
Cancel out the x terms and you get
(2x5)/(x3)
