вас, , надо решить уравнение :

(3x - 2)²(2x - 18) = (3x - 2)(2x - 18)²
(3x-2)²(2x-18) - (3x-2)(2x-18)² = 0
(3x-2)(2x-18)(3x-2 - 2x + 18) = 0
2(3x - 2)(x-9)(x + 16) = 0
(3x - 2)(x - 9)(x + 16) = 0
или  3x - 2 = 0       или   x - 9 = 0            или  x + 16 = 0
        x₁ = 2/3                   x₂ = 9                        x₃ = - 16
