⇔ x = ((((√3) (√(2+c^2 +4)) +9c))^(1/3) /( ((18))^(1/3) )) − ((2)^(1/3) /( ((3(√3) (√(27c^2 +4)) +27c))^(1/3) ))

$$\Leftrightarrow\:\mathrm{x}\:=\:\frac{\sqrt[{\mathrm{3}}]{\sqrt{\mathrm{3}}\:\sqrt{\mathrm{2}+\mathrm{c}^{\mathrm{2}} +\mathrm{4}}\:+\mathrm{9c}}}{\:\sqrt[{\mathrm{3}}]{\mathrm{18}}}\:−\:\frac{\sqrt[{\mathrm{3}}]{\mathrm{2}}}{\:\sqrt[{\mathrm{3}}]{\mathrm{3}\sqrt{\mathrm{3}}\:\sqrt{\mathrm{27c}^{\mathrm{2}} +\mathrm{4}}\:+\mathrm{27c}}}\: \\ $$

x^3 +x=c

$${x}^{\mathrm{3}} +{x}={c} \\ $$
