Find roots of polynomial $$ p(x) = x^3-2x^2-60x-216 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 10.0791\\[1 em]x_2 &= -4.0396+2.2611i\\[1 em]x_3 &= -4.0396-2.2611i \end{aligned} $$Explanation
Polynomial $ x^3-2x^2-60x-216 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
