Find roots of polynomial $$ p(x) = 42x^6-600x^5+20x^4+8x^3+21x^2+18x+1 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -0.0597\\[1 em]x_2 &= -0.3386\\[1 em]x_3 &= 0.4951\\[1 em]x_4 &= 14.2512\\[1 em]x_5 &= -0.0312+0.4075i\\[1 em]x_6 &= -0.0312-0.4075i \end{aligned} $$Explanation
Polynomial $ 42x^6-600x^5+20x^4+8x^3+21x^2+18x+1 $ has no rational roots that can be found using Rational Root Test, so the roots were found using Newton method.
