Find roots of polynomial $$ p(x) = 5x^4-16x^3+15x^2-6x+5 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -0.0028+0.6156i\\[1 em]x_2 &= -0.0028-0.6156i\\[1 em]x_3 &= 1.6028+0.2646i\\[1 em]x_4 &= 1.6028-0.2646i \end{aligned} $$Explanation
Polynomial $ 5x^4-16x^3+15x^2-6x+5 $ has no rational roots that can be found using Rational Root Test, so the roots were found using quartic formulas.
