I need help with a couple rational function questions

[MooreC1]

My book says to find t for the given value of g(t).

1. g(t) = t-1 / t-5 g(t) =-3

2. g(t) = 2t^2+8t-40 / t-4 g(t) =5

help me please, I don't understand them.

1) Plug "-3" in for "g(t)", and solve the rational equation.

. . . . .-3 = t - (1/t) - 5

. . . . .0 = t - (1/t) - 2

. . . . .0 = t² - 2t - 1

Then apply the Quadratic Formula.

2) Plug "5" in. Solve as in (1).
