1/(x-1)^2 + 3/x-1 - 10 = 0

Приводим к общему знаменателю:

1/(x-1)^2 + 3(x-1)/(x-1)^2 - 10 (x-1)^2/(x-1)^2 = 0 (домножаем многочлен на (x-1)^2, где x ≠ 1

-10(x-1)^2  + 3(x-1) + 1 = 0

-10(x^2-2x+1)+3x-3+1=0

-10x^2+20x-10+3x-3+1=0

-10x^2+23x-12=0 (домножаем на -1)

10x^2-23x+12=0

D=(-23)^2-4*10*12=529-480=49=7^2

x1=23+7/20=30/20=3/2=1,5

x2=23-7/20=16/20=8/10=0,8

Ответ: 0,8; 1,5.
