Find roots of polynomial $$ p(x) = 10x^4-24x^3+21x^2-2x+5 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -0.0788+0.4612i\\[1 em]x_2 &= -0.0788-0.4612i\\[1 em]x_3 &= 1.2788+0.8055i\\[1 em]x_4 &= 1.2788-0.8055i \end{aligned} $$Explanation
Polynomial $ 10x^4-24x^3+21x^2-2x+5 $ has no rational roots that can be found using Rational Root Test, so the roots were found using quartic formulas.
