Find roots of polynomial $$ p(x) = 18x^6-3x^4+6x^2-1 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 0.4083\\[1 em]x_2 &= -0.4083\\[1 em]x_3 &= -0.5373+0.5373i\\[1 em]x_4 &= -0.5373-0.5373i\\[1 em]x_5 &= 0.5373+0.5373i\\[1 em]x_6 &= 0.5373-0.5373i \end{aligned} $$Explanation
Polynomial $ 18x^6-3x^4+6x^2-1 $ has no rational roots that can be found using Rational Root Test, so the roots were found using Newton method.
