x+17/x^2-6x+8 + x-2/x-4 = x-4/x-2

32/t^2+3t+2 - 3 = t-3/t+1

r(3-r) + (2r+2)^2 = 0

Can somebody help me with these please our midterm is tomorrow and if questions like these turn up (which is very likely) then my goose is cooked.

EDIT: I grouped them together to make things clearer:

(x+17)/(x^2-6x+8) + (x-2)/(x-4) = (x-4)/(x-2)

32/(t^2+3t+2) - 3 = (t-3)/(t+1)

r(3-r) + (2r+2)^2 = 0
