Find roots of polynomial $$ p(x) = x^3-20x^2+476x-1760 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 4.3097\\[1 em]x_2 &= 7.8451+18.6235i\\[1 em]x_3 &= 7.8451-18.6235i \end{aligned} $$Explanation
Polynomial $ x^3-20x^2+476x-1760 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
