Find roots of polynomial $$ p(x) = 2x^3+9x^2+26x+24 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -1.3803\\[1 em]x_2 &= -1.5599+2.5022i\\[1 em]x_3 &= -1.5599-2.5022i \end{aligned} $$Explanation
Polynomial $ 2x^3+9x^2+26x+24 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
