Find roots of polynomial $$ p(x) = x^3+4x^2+53x-238 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 3.151\\[1 em]x_2 &= -3.5755+7.9214i\\[1 em]x_3 &= -3.5755-7.9214i \end{aligned} $$Explanation
Polynomial $ x^3+4x^2+53x-238 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
