Explicación paso a paso:

$\left ( 2x -4\right )\left [ \left ( 6x \right ) ^2-5x-2\right ]\\\\\left ( 2x-4 \right )\left ( 36x^2-5x-2 \right )\\\\\left ( 2x*36x^2 \right )+\left ( 2x*-5x \right )+\left ( 2x*-2 \right )+\left ( -4*36x^2 \right )+\left ( -4*-5x \right )+\left ( -4*-2 \right )\\\\\left ( 72x^3 \right )+\left ( -10x^2 \right )+\left ( -4x \right )+\left ( -144x^2 \right )+\left ( 20x \right )+\left ( 8 \right )\\\\72x^3 -10x^2 -4x -144x^2 + 20x +8 \\\\72x^3-154x^2+16x+8$
