Answer 1

$(x - 2)(x + 2)( {x}^{2} + 4) - ( {x}^{2} - 1)^{2} + 2 {(x + 1)}^{2}$

$= {(x}^{2} - 4)( {x}^{2} + 4) - ( {x}^{4} - 2 {x}^{2} + 1) + 2( {x}^{2} + 2x + 1)$

$= {x}^{4} - 16 - {x}^{4} + 2 {x}^{2} - 1 + 2 {x}^{2} + 4x + 2$

$= 4 {x}^{2} + 4x - 15$

Answer 2

sper sa intelegi care este $x^2$ si care este 2x


Succes! :)
