How can I find the roots of $x^{3} - 3 x + 1$ using Cardano's formula?
So far, I found that
$x = \sqrt[3]{\frac{- 1 + \sqrt{- 3}}{2}} + \sqrt[3]{\frac{- 1 - \sqrt{- 3}}{2}}$
$x = \sqrt[3]{\frac{- 1 + i \sqrt{3}}{2}} + \sqrt[3]{\frac{- 1 - i \sqrt{3}}{2}}$
$x = \sqrt[3]{\frac{- 1}{2} + \frac{i \sqrt{- 3}}{2}} + \sqrt[3]{\frac{- 1}{2} - \frac{i \sqrt{- 3}}{2}}$
I am now trying to express each cubic radicand in their exponential form.

Older railroad tracks in the U.S. are made of 12-m-long pieces of steel. When the tracks are laid, gaps are left between the sections o prevent buckling when the steel thermally expands. Part A If a track is laid at $16^{o} C$ , how large should the gaps be if the track is not to buckle when the temperature is as high as $50^{o} C$ ? The coefficient of linear expansion of soft steel is $1.1 \times 10^{- 5} C^{- 1}$
