Nevermind, I figured it out.
My second term needs to be Bx+Ca/(x^2 + a^2)

You have some extra stuff in there that you don't need, and you are missing some parentheses. The second term should be
[tex]\frac{Bx + C}{x^2 + a^2}[/tex]
If you write this without using LaTeX, it should be
(Bx + C)/(x
^{2} + a
^{2})
