Find roots of polynomial $$ p(x) = 5x^4-16x^3+18x^2-6x+5 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 0.0297+0.5681i\\[1 em]x_2 &= 0.0297-0.5681i\\[1 em]x_3 &= 1.5703+0.7899i\\[1 em]x_4 &= 1.5703-0.7899i \end{aligned} $$Explanation
Polynomial $ 5x^4-16x^3+18x^2-6x+5 $ has no rational roots that can be found using Rational Root Test, so the roots were found using quartic formulas.
