Find roots of polynomial $$ p(x) = s^3+2s^2+12s+1 $$
Answer
The roots of polynomial $ p(s) $ are:
$$ \begin{aligned}s_1 &= -0.0845\\[1 em]s_2 &= -0.9578+3.3047i\\[1 em]s_3 &= -0.9578-3.3047i \end{aligned} $$Explanation
Polynomial $ s^3+2s^2+12s+1 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
