Find roots of polynomial $$ p(x) = x^4-9x^3+24x^2+16x-6 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 0.2738\\[1 em]x_2 &= -0.7604\\[1 em]x_3 &= 4.7433+2.515i\\[1 em]x_4 &= 4.7433-2.515i \end{aligned} $$Explanation
Polynomial $ x^4-9x^3+24x^2+16x-6 $ has no rational roots that can be found using Rational Root Test, so the roots were found using quartic formulas.
