You can put this solution on YOUR website!
t%5E2-9=%28t%2B3%29%28t-3%29
2t%2B6=2%28t%2B3%29
%285t%29%2F%282t%2B6%29-%284%29%2F%28t%5E2-9%29=5%2F2
%285t%29%2F%282%28t%2B3%29%29-%284%29%2F%28%28t%2B3%29%28t-3%29%29=5%2F2
Multiply both sides by 2%28t-3%29%2A%28t%2B3%29,
5t%28t-3%29-4%282%29=5%28t-3%29%28t%2B3%29
5t%5E2-15t-8=5t%5E2-45
-15t=8-45
-15t=-37
t=37%2F15
