Riješi y=(x+1)(x^2-x+1)/x^3Rightarrow

$$y = \frac { ( x + 1 ) ( x ^ { 2 } - x + 1 ) } { x ^ { 3 } } \Rightarrow$$

Izračunaj x (complex solution)

$$x=e^{\frac{2\pi i}{3}}\left(y-1\right)^{-\frac{1}{3}}$$

$$x=\left(y-1\right)^{-\frac{1}{3}}$$

$$x=e^{\frac{4\pi i}{3}}\left(y-1\right)^{-\frac{1}{3}}\text{, }y\neq 1$$

Izračunaj x

$$x=\frac{1}{\sqrt[3]{y-1}}$$

$$y\neq 1$$

Izračunaj y

$$y=1+\frac{1}{x^{3}}$$

$$x\neq 0$$
