Find roots of polynomial $$ p(x) = x^3+6x^2+9x-2 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 0.1958\\[1 em]x_2 &= -3.0979+0.785i\\[1 em]x_3 &= -3.0979-0.785i \end{aligned} $$Explanation
Polynomial $ x^3+6x^2+9x-2 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
