Find roots of polynomial $$ p(x) = x^3+2 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -1.2599\\[1 em]x_2 &= 0.63+1.0911i\\[1 em]x_3 &= 0.63-1.0911i \end{aligned} $$Explanation
Polynomial $ x^3+2 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
