4t+12
_____
t^2-9
Yes those are the final answers. I am a bit confused. Was it two questions like I did or was it supposed to be like this:
$\displaystyle
\frac {4(t+3)}{(t+3)(t-3)}$
If it was one question and it is a division statement, then you can also cancel out the (t+3) terms to get a final answer of:
$\displaystyle
\frac {4}{t-3}$
