Simplify [ 2/x + 3x ] [ 4/x riased to 2 + 9x raised to 2 - 6 ] pls send it fast

Answer 1

$( \frac{2}{x} + 3x)( { (\frac{4}{x} )}^{2} + 9 {x}^{2} - 6)$

$= ( \frac{2}{x} + 3x)( {( \frac{2}{x}) }^{2} - \frac{2}{x} \times 3x + (3x)^{2} )$

$= ( \frac{2}{x} )^{3} + (3x)^{3}$

$= \frac{8}{ {x}^{3} } + 27 {x}^{3}$
