Find roots of polynomial $$ p(x) = x^3-x-11 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 2.3737\\[1 em]x_2 &= -1.1868+1.796i\\[1 em]x_3 &= -1.1868-1.796i \end{aligned} $$Explanation
Polynomial $ x^3-x-11 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
