Ответ:
\[2x^{2} - 4x = x(6x - 3)\]
\[2x^{2} - 4x = 6x^{2} - 3x\]
\[4x^{2} + x = 0\]
\[4x\left( x + \frac{1}{4} \right) = 0\]
\[x = 0;\ \ x = \frac{1}{4} = 0,25.\]
\[2x^{2} - 4x = x(6x - 3)\]
\[2x^{2} - 4x = 6x^{2} - 3x\]
\[4x^{2} + x = 0\]
\[4x\left( x + \frac{1}{4} \right) = 0\]
\[x = 0;\ \ x = \frac{1}{4} = 0,25.\]
