Riješite za x (complex solution)
x=-\frac{\left(1+\sqrt{3}i\right)\left(-\sqrt{3}\sqrt[3]{6\sqrt{9978}-865}i-\sqrt[3]{6\sqrt{9978}-865}-7\sqrt{3}i+2\sqrt[3]{-6\sqrt{9978}-865}+7\right)}{24}\approx -1,291773143-1,639054221i
x=\frac{\sqrt[3]{6\sqrt{9978}-865}+\sqrt[3]{-6\sqrt{9978}-865}-7}{6}\approx 0,315349165+2,566926718i
x=-\frac{\left(-\sqrt{3}i+1\right)\left(-\sqrt[3]{6\sqrt{9978}-865}+2\sqrt[3]{-6\sqrt{9978}-865}+7+\sqrt{3}\sqrt[3]{6\sqrt{9978}-865}i+7\sqrt{3}i\right)}{24}\approx -2,523576022-0,927872497i
Riješite za x
x=\frac{-\sqrt[3]{6\sqrt{9978}+865}-\sqrt[3]{865-6\sqrt{9978}}-7}{6}\approx -4,13069833
