Explicación paso a paso:

hola °

Efectuar !

$a = x( {x}^{2} - 2x + 4) - ( {x}^{3} - 2 {x}^{2} )$

$a = {x}^{3} - 2 {x}^{2} + 4x - {x}^{3} + 2 {x}^{2}$

$a = ( {x}^{3} - {x}^{3} ) + ( - 2 {x}^{2} + 2 {x}^{2} ) + 4x$

$a = 4x$

Nos pide hallar A^2

$= {(4x)}^{2}$

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

$= 16 {x}^{2}$
