Find roots of polynomial $$ p(x) = x^3-18x^2+61x-127 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 14.3701\\[1 em]x_2 &= 1.815+2.3545i\\[1 em]x_3 &= 1.815-2.3545i \end{aligned} $$Explanation
Polynomial $ x^3-18x^2+61x-127 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
