Gjej x, a
x = \frac{\sqrt[3]{12 \sqrt{8115} + 1081} + \sqrt[3]{1081 - 12 \sqrt{8115}} + 1}{12} \approx 1.167327637
a=\frac{-2\sqrt[3]{12\sqrt{8115}+1081}-\left(12\sqrt{8115}+1081\right)^{\frac{2}{3}}-2\sqrt[3]{1081-12\sqrt{8115}}-\left(1081-12\sqrt{8115}\right)^{\frac{2}{3}}-147}{576}\approx -0.590663453
