Find roots of polynomial $$ p(x) = 7x^5+x^3-2x+13 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -1.1452\\[1 em]x_2 &= 0.8834+0.6407i\\[1 em]x_3 &= 0.8834-0.6407i\\[1 em]x_4 &= -0.3108+1.1248i\\[1 em]x_5 &= -0.3108-1.1248i \end{aligned} $$Explanation
Polynomial $ 7x^5+x^3-2x+13 $ has no rational roots that can be found using Rational Root Test, so the roots were found using Newton method.
