$(t+1)/(t-6)$

You have to factorize the top and bottom look for a factor that multiples into -6 and adds into -5

The possible factors are 6,1 and 3,2. We know that -6 and +1 add to -5 and multiply -6. Likewise the factors -6 and -1 add to -7 and multiply to 6.

$((t-6)(t+1))/((t-6)(t-1)$

can remove the common factor of $(t-6)$ from denominator and numerator to get

$(t+1)/(t-6)$
