Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 2.1603\\[1 em]x_2 &= 6.2324+2.341i\\[1 em]x_3 &= 6.2324-2.341i \end{aligned} $$Explanation
Polynomial $ -8x^3+117x^2-570x+766 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
