Find roots of polynomial $$ p(x) = 3x^5-x^4-x^3+x+1 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -0.6762\\[1 em]x_2 &= 0.8386+0.4968i\\[1 em]x_3 &= 0.8386-0.4968i\\[1 em]x_4 &= -0.3338+0.6384i\\[1 em]x_5 &= -0.3338-0.6384i \end{aligned} $$Explanation
Polynomial $ 3x^5-x^4-x^3+x+1 $ has no rational roots that can be found using Rational Root Test, so the roots were found using Newton method.
