Answer 2

=>

$\sqrt[3]{x {}^{2} - d } = - 2 \: x \: apartine \: n$

$1 \times 4 \times 5 + 1 \times ( - 4) \times 0 + 2 \times 0 \times ( - 2) - 0 \times 4 \times 2 - ( - 2) \times ( - 4) \times 1 - 5 \times 0 \times 1$

$d = 20 - 8 = 12$

$\sqrt[3]{ {x}^{2} - d} = \sqrt[3]{ {x}^{2} - 12 } = - 2$

${x}^{2} - 12 = - 8$

${x}^{2} = 12 - 8$

${x}^{2} = 4$

$x = 2$
