Find roots of polynomial $$ p(x) = 2x^3-x^2-23x+12 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 0.5223\\[1 em]x_2 &= 3.3783\\[1 em]x_3 &= -3.4006 \end{aligned} $$Explanation
Polynomial $ 2x^3-x^2-23x+12 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
