Find roots of polynomial $$ p(x) = x^4-16x^3+73x^2+112x-560 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 2.6458\\[1 em]x_2 &= -2.6458\\[1 em]x_3 &= 8+4i\\[1 em]x_4 &= 8-4i \end{aligned} $$Explanation
Polynomial $ x^4-16x^3+73x^2+112x-560 $ has no rational roots that can be found using Rational Root Test, so the roots were found using quartic formulas.
