Leystu fyrir x (complex solution)
x=-\frac{\left(1+\sqrt{3}i\right)\left(-\sqrt{3}\sqrt[3]{9\sqrt{193}-125}i-2\sqrt[3]{9\sqrt{193}+125}-\sqrt[3]{9\sqrt{193}-125}-1+\sqrt{3}i\right)}{12}\approx 1.33040122+1.910261704i
x=\frac{\sqrt[3]{9\sqrt{193}-125}-\sqrt[3]{9\sqrt{193}+125}+1}{3}\approx -1.66080244
