(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

This is a problem off a multiple choice practice test:

lim t->3 ( 1/(t^2-3t) - 2/(t^2-9) =

The solutions are:

(a) 0 (b) -1/9 (c) -1/18 (d)1 (e) 1/3

The correct answer is (c).

Can someone explain to me how to solve it? Any help would be very appreciated. You don't need to explain how to do limits. I just need to know how to manipulate the equation so that it's not indeterminate.

2. Relevant equations

NA

3. The attempt at a solution

I tried multiplying by the conjugate with no success.
