Задание:
(x-3) / (xy-x^2) — (3-y) / (xy-y^2)
Решение:
(х-3/xy-x^2) — (3-y/xy-y^2)=(x-3/x (y-x) — (3-y/y (x-y)=xy-3y+3x-x/xy (y-x)=3x-3y/xy (y-x)=-3 (x-y) / xy (x-y)=-3/xy
Знаете другой ответ?
(x-3) / (xy-x^2) — (3-y) / (xy-y^2)
(х-3/xy-x^2) — (3-y/xy-y^2)=(x-3/x (y-x) — (3-y/y (x-y)=xy-3y+3x-x/xy (y-x)=3x-3y/xy (y-x)=-3 (x-y) / xy (x-y)=-3/xy
