Find roots of polynomial $$ p(x) = 42x^6+12x^5+20x^4+8x^3+21x^2+12x+5 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -0.3818+0.3817i\\[1 em]x_2 &= -0.3818-0.3817i\\[1 em]x_3 &= -0.3303+0.6472i\\[1 em]x_4 &= -0.3303-0.6472i\\[1 em]x_5 &= 0.5692+0.6706i\\[1 em]x_6 &= 0.5692-0.6706i \end{aligned} $$Explanation
Polynomial $ 42x^6+12x^5+20x^4+8x^3+21x^2+12x+5 $ has no rational roots that can be found using Rational Root Test, so the roots were found using Newton method.
