The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -0.3425\\[1 em]x_2 &= -0.682+0.6025i\\[1 em]x_3 &= -0.682-0.6025i\\[1 em]x_4 &= 0.0307+1.0229i\\[1 em]x_5 &= 0.0307-1.0229i\\[1 em]x_6 &= 0.9892+0.8396i\\[1 em]x_7 &= 0.9892-0.8396i \end{aligned} $$Polynomial $ 6x^7-2x^6+4x^5+2x^4+7x^3+6x^2+10x+3 $ has no rational roots that can be found using Rational Root Test, so the roots were found using Newton method.
