1) (x^2 - 5x) + 5 - x = 0x^2 - 5x + 5 - x = 0x^2 - 6x + 5 = 0(x - 5)(x - 1) = 0x = 5 или x = 1
2) x^2 - 9x - (x - 9) = 0x^2 - 9x - x + 9 = 0x^2 - 10x + 9 = 0(x - 9)(x - 1) = 0x = 9 или x = 1
Таким образом, решения уравнений: x = 5, x = 1, x = 9.
1) (x^2 - 5x) + 5 - x = 0
x^2 - 5x + 5 - x = 0
x^2 - 6x + 5 = 0
(x - 5)(x - 1) = 0
x = 5 или x = 1
2) x^2 - 9x - (x - 9) = 0
x^2 - 9x - x + 9 = 0
x^2 - 10x + 9 = 0
(x - 9)(x - 1) = 0
x = 9 или x = 1
Таким образом, решения уравнений: x = 5, x = 1, x = 9.
