Find roots of polynomial $$ p(x) = x^4+4x^3+2x^2+3x+1 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -0.3632\\[1 em]x_2 &= -3.657\\[1 em]x_3 &= 0.0101+0.8676i\\[1 em]x_4 &= 0.0101-0.8676i \end{aligned} $$Explanation
Polynomial $ x^4+4x^3+2x^2+3x+1 $ has no rational roots that can be found using Rational Root Test, so the roots were found using quartic formulas.
