Find roots of polynomial $$ p(x) = -x^3+3x^2-2x+5 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 2.9042\\[1 em]x_2 &= 0.0479+1.3113i\\[1 em]x_3 &= 0.0479-1.3113i \end{aligned} $$Explanation
Polynomial $ -x^3+3x^2-2x+5 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
