Find roots of polynomial $$ p(x) = 2x^3-2x^2-x+5 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -1.189\\[1 em]x_2 &= 1.0945+0.9512i\\[1 em]x_3 &= 1.0945-0.9512i \end{aligned} $$Explanation
Polynomial $ 2x^3-2x^2-x+5 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
