even though by the time I get a reply or get back here it'll be too late. I think I might have copied this one wrong....

Hello,

maybe you mean:

$\displaystyle \frac{t^2 + 5t}{t^2+7t+6} - \frac{7t-3}{t^2+7t-6}$ . If so:

Factor all numerators and denominators (if possible):

$\displaystyle \frac{t(t + 5)}{(t+1)(t+6)} - \frac{7t-3}{t^2+7t-6} = \frac{t(t+5)(t^2+7t-6)-(7t-3)(t+1)(t+6)}{(t+1)(t+6)(t^2+7t-6)}$

Expand the brackets in the numerator and collect like terms.

In my opinion there must be a typo in the 2nd summand ...
