Find roots of polynomial $p (x) = x^{3} - 4 x^{2} - 2$

Answer

The roots of polynomial $p (x)$ are:
$x_{1} x_{2} x_{3} = 4.1179 = - 0.059 + 0.6944 i = - 0.059 - 0.6944 i$

Explanation

Polynomial $x^{3} - 4 x^{2} - 2$ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
