Find roots of polynomial $$ p(x) = x^3+48x^2+720x-320 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 0.4319\\[1 em]x_2 &= -24.216+12.43i\\[1 em]x_3 &= -24.216-12.43i \end{aligned} $$Explanation
Polynomial $ x^3+48x^2+720x-320 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
