Lös ut x (complex solution)
x=-\frac{\left(1+\sqrt{3}i\right)\left(-\sqrt{3}\sqrt[3]{9\sqrt{79}+80}i-\sqrt{3}i-\sqrt[3]{9\sqrt{79}+80}+2\sqrt[3]{80-9\sqrt{79}}+1\right)}{12}\approx -1,268828086+1,513974228i
x = \frac{\sqrt[3]{9 \sqrt{79} + 80} + \sqrt[3]{80 - 9 \sqrt{79}} - 1}{3} \approx 1,537656172
