Answer 2

Answer:

${4x}^{3} = 2x$

${4x}^{3} - 2x = 0$

$2x( {2x}^{2} - 1) = 0$

$(2x)( {2x}^{2} - 1) = 0$

$2x = 0 \: \: \: \: \: \: \: and \: \: \: {2x}^{2} - 1 = 0$

$x = \frac{0}{2} \: \: \: \: \: and \: \: \: {2x}^{2} = 1$

$x = 0 \: \: \: and \: \: {x}^{2} = \frac{1}{2}$

$x = 0 \: \: \: and \: \: \: x = \sqrt{ \frac{1}{2} }$

therefore x = { 0 , √1/2 }
