!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
(x-3)/(x-2) + (x-2)/(x-3) = 2 1/2
ОДЗ x≠2 x≠3
очень много уравнений идет на выражение x + 1/x = 5/2
замена (x-3)/(x-2) = t
t + 1/t = 5/2
(2t² - 5t + 2)/t = 0
D=25 - 16 = 9
t12=(5+-3)/4 = 2 1/2
1/ t=2
(x-3)/(x-2)=2
x-3 = 2x - 4
x = 1
2/ (x-3)/(x-2) = 1/2
2x - 6 = x - 2
x=4
ответ -1 и 4
--------------------
ну можно немного упростить
(x-3)/(x-2) = (x-2 -1)/(x-2) = 1 - 1/(x-2)
(x-2)/(x-3) = (x-3 + 1)/(x-3) = 1 + 1/(x-3)
1/(x-3) - 1/(x-2) = 1/2 и решать уже такое
