Find roots of polynomial $$ p(x) = -x^3+2x^2-10x-7 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -0.6047\\[1 em]x_2 &= 1.3024+3.1431i\\[1 em]x_3 &= 1.3024-3.1431i \end{aligned} $$Explanation
Polynomial $ -x^3+2x^2-10x-7 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
