Find roots of polynomial $$ p(x) = x^4-x^3+17x^2+7 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -0.013+0.6491i\\[1 em]x_2 &= -0.013-0.6491i\\[1 em]x_3 &= 0.513+4.0425i\\[1 em]x_4 &= 0.513-4.0425i \end{aligned} $$Explanation
Polynomial $ x^4-x^3+17x^2+7 $ has no rational roots that can be found using Rational Root Test, so the roots were found using quartic formulas.
