Find roots of polynomial $$ p(x) = 6x^5-28x+15 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 0.5461\\[1 em]x_2 &= -1.581\\[1 em]x_3 &= 1.2842\\[1 em]x_4 &= -0.1247+1.4964i\\[1 em]x_5 &= -0.1247-1.4964i \end{aligned} $$Explanation
Polynomial $ 6x^5-28x+15 $ has no rational roots that can be found using Rational Root Test, so the roots were found using Newton method.
