Find roots of polynomial $$ p(x) = -2x^3-3x^2-11x+6 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 0.4673\\[1 em]x_2 &= -0.9837+2.3349i\\[1 em]x_3 &= -0.9837-2.3349i \end{aligned} $$Explanation
Polynomial $ -2x^3-3x^2-11x+6 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
