Find roots of polynomial $$ p(x) = x^6+4x^5+3x^4-2x^3-4x^2+4x+7 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -1.1155\\[1 em]x_2 &= -2.9211\\[1 em]x_3 &= 0.8957+0.5705i\\[1 em]x_4 &= 0.8957-0.5705i\\[1 em]x_5 &= -0.8774+1.0655i\\[1 em]x_6 &= -0.8774-1.0655i \end{aligned} $$Explanation
Polynomial $ x^6+4x^5+3x^4-2x^3-4x^2+4x+7 $ has no rational roots that can be found using Rational Root Test, so the roots were found using Newton method.
