Find roots of polynomial $$ p(x) = x^4+36x^3+296x^2+160 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -12.8016\\[1 em]x_2 &= -23.2635\\[1 em]x_3 &= 0.0325+0.7323i\\[1 em]x_4 &= 0.0325-0.7323i \end{aligned} $$Explanation
Polynomial $ x^4+36x^3+296x^2+160 $ has no rational roots that can be found using Rational Root Test, so the roots were found using quartic formulas.
