Find roots of polynomial $$ p(x) = 2s^3+31s^2+72s+99 $$
Answer
The roots of polynomial $ p(s) $ are:
$$ \begin{aligned}s_1 &= -13.0284\\[1 em]s_2 &= -1.2358+1.5074i\\[1 em]s_3 &= -1.2358-1.5074i \end{aligned} $$Explanation
Polynomial $ 2s^3+31s^2+72s+99 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
