Find roots of polynomial $$ p(x) = x^4-4x^3+10x^2+16x-16 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 0.7402\\[1 em]x_2 &= -1.4802\\[1 em]x_3 &= 2.37+2.9977i\\[1 em]x_4 &= 2.37-2.9977i \end{aligned} $$Explanation
Polynomial $ x^4-4x^3+10x^2+16x-16 $ has no rational roots that can be found using Rational Root Test, so the roots were found using quartic formulas.
