Find roots of polynomial $$ p(x) = x^3-5 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 1.71\\[1 em]x_2 &= -0.855+1.4809i\\[1 em]x_3 &= -0.855-1.4809i \end{aligned} $$Explanation
Polynomial $ x^3-5 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
