$6 {x}^{3} - 24x = 0 \\ 6x( {x}^{2} - 4) = 0 \\ x = 0 \\ {x}^{2} = 4 \\ x_{1} = 0 \\ x_{2/3} =±2$

Ответ: -2, 0, 2

$25 {x}^{3} - 10 {x}^{2} + x = 0 \\ x(25 {x}^{2} - 10x + 1) = 0 \\ x_{1} = 0 \\ (5x)^{2} - 2 \times 5x + 1 = 0 \\ (5x - 1)^{2} = 0 \\ 5x - 1 = 0 \\ 5x = 1 \\ x _{2}= 0.2$

Ответ: 0, 0.2
