hola °

Efectuar !

[tex] a = x( {x}^{2} - 2x + 4) - ( {x}^{3} - 2 {x}^{2} )[/tex]

[tex]a = {x}^{3} - 2 {x}^{2} + 4x - {x}^{3} + 2 {x}^{2} [/tex]

[tex]a = ( {x}^{3} - {x}^{3} ) + ( - 2 {x}^{2} + 2 {x}^{2} ) + 4x[/tex]

[tex]a = 4x[/tex]

Nos pide hallar A^2

[tex] = {(4x)}^{2} [/tex]

[tex] = {4}^{2} {x}^{2} [/tex]

[tex] = 16 {x}^{2} [/tex]
