(x - 3)(x - 4)(x - 5) = (x - 2)(x - 4)(x - 5)
(x - 3)(x - 4)(x - 5) - (x - 2)(x - 4)(x - 5) = 0
(x - 4)(x - 5)((x - 3) - (x - 2)) = 0
(x - 4)(x - 5)(x - 3 - x + 2) = 0
(x - 4)(x - 5)(0 - 1) = 0
-(x - 4)(x - 5) = 0
(x - 4)(x - 5) = 0
Произведение множителей равно нулю, если любой из множителей равен нулю:
x = 4 и x = 5
Ответ: x = 4; 5.
