I-solve ang x (complex solution)
x=\frac{4^{\frac{2}{3}}\left(1+\sqrt{3}i\right)\left(\sqrt[3]{\sqrt{6}+2}+2\sqrt[3]{\sqrt{6}-2}+\sqrt{3}\sqrt[3]{\sqrt{6}+2}i\right)}{32}\approx -0.138393446+0.65761557i
x=\frac{4^{\frac{2}{3}}\left(\sqrt[3]{\sqrt{6}+2}-\sqrt[3]{\sqrt{6}-2}\right)}{8}\approx 0.276786891
x=\frac{4^{\frac{2}{3}}\left(-\sqrt{3}i+1\right)\left(-\sqrt{3}\sqrt[3]{\sqrt{6}+2}i+\sqrt[3]{\sqrt{6}+2}+2\sqrt[3]{\sqrt{6}-2}\right)}{32}\approx -0.138393446-0.65761557i
I-solve ang x
x = \frac{4 ^ {\frac{2}{3}} {(\sqrt[3]{\sqrt{6} + 2} + \sqrt[3]{2 - \sqrt{6}})}}{8} \approx 0.276786891
