Find roots of polynomial $p (x) = 4 x^{3} + 12 x^{2} + 12 x + 10$

Answer

The roots of polynomial $p (x)$ are:
$x_{1} x_{2} x_{3} = - 2.1447 = - 0.4276 + 0.9914 i = - 0.4276 - 0.9914 i$

Explanation

Polynomial $4 x^{3} + 12 x^{2} + 12 x + 10$ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
