(x-1).(1-x)²(x-2)³/(2-x)².(1-x)³
(x-1).(x-2)³/(2-x)².(1-x)
(x-2)²/2-x
x-2

(1/(x - 1))^-1 . ((1 - x)/(2 - x))^2 . ((x - 2)/(1 - x))^3
= (x - 1)^1 . (1 - x)^2 . (2 - x)^-2 . (x - 2)^3 . (1 - x)^-3
= -(1 - x) . (1 - x)^2 . (2 - x)^-2 . (-(2 - x))^3 . (1 - x)^-3
= - (1 - x)^(1 + 2 + (-3)) . (2 - x)^-2 . (-1)^3 . (2 - x)^3
= - (1 - x)^0 . -1 . (2 - x)^(-2 + 3)
= - (1) . -1 . (2 - x)^1
= 2 - x
