Which sum or difference is modeled by the algebra tiles? $a. \: {x}^{2} + 4x - 2) + ( {x}^{2} - 2x - 4) = {2x}^{2} + 2x + 2$

$b. \: ( {x}^{2} + 4x - 2) + ( {x}^{2} + 2x + 4) = {2x}^{2} + 2x + 2$
$c. \: ( {x}^{2} + 4x - 2) - ( { - x}^{2} + 2x - 4) = {2x}^{2} + 2x + 2$
$d. \: ( {x}^{2} + 4x - 2) - ( { - x}^{2} - 2x + 4) = {2x}^{2} + 2x + 2$
