Find roots of polynomial $$ p(x) = x^6+3x^4+2x^2+1 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 0.3989+0.7048i\\[1 em]x_2 &= 0.3989-0.7048i\\[1 em]x_3 &= -0.3989+0.7048i\\[1 em]x_4 &= -0.3989-0.7048i\\[1 em]x_5 &= 1.5247i\\[1 em]x_6 &= -1.5247i \end{aligned} $$Explanation
Polynomial $ x^6+3x^4+2x^2+1 $ has no rational roots that can be found using Rational Root Test, so the roots were found using Newton method.
