Lös ut x (complex solution)
x=-\frac{2^{\frac{2}{3}}\left(1+\sqrt{3}i\right)\left(-\sqrt[3]{3\left(9\sqrt{23}+25\sqrt{3}\right)}i-\sqrt{3}\sqrt[3]{2}i-\sqrt[3]{3\sqrt{69}+25}+2\sqrt[3]{25-3\sqrt{69}}+\sqrt[3]{2}\right)}{24}\approx -0,877438833+0,744861767i
x=\frac{2^{\frac{2}{3}}\left(\sqrt[3]{3\sqrt{69}+25}+\sqrt[3]{25-3\sqrt{69}}-\sqrt[3]{2}\right)}{6}\approx 0,754877666
