Rozwiąż x^2/4=x^3/8+3

$$\frac { x ^ { 2 } } { 4 } = \frac { x ^ { 3 } } { 8 } + 3$$

Rozwiąż względem x (complex solution)

$$x=\frac{\sqrt{3}\sqrt[3]{36\sqrt{77}-316}i}{6}-\frac{\sqrt{3}\sqrt[3]{-36\sqrt{77}-316}i}{6}-\frac{\sqrt[3]{36\sqrt{77}-316}}{6}-\frac{\sqrt[3]{-36\sqrt{77}-316}}{6}+\frac{2}{3}\approx 1,941492383-2,477185533i$$

$$x=\frac{\sqrt[3]{36\sqrt{77}-316}+\sqrt[3]{-36\sqrt{77}-316}+2}{3}\approx 2,17455941+2,611746844i$$

$$x=-\frac{\sqrt{3}\sqrt[3]{36\sqrt{77}-316}i}{6}+\frac{\sqrt{3}\sqrt[3]{-36\sqrt{77}-316}i}{6}-\frac{\sqrt[3]{36\sqrt{77}-316}}{6}-\frac{\sqrt[3]{-36\sqrt{77}-316}}{6}+\frac{2}{3}\approx -2,116051793-0,134561311i$$

Rozwiąż względem x

$$x=\frac{-\sqrt[3]{36\sqrt{77}+316}-\sqrt[3]{316-36\sqrt{77}}+2}{3}\approx -2,349118821$$
