Find roots of polynomial $$ p(x) = 2x^3-80x^2-50000000 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 306.3615\\[1 em]x_2 &= -133.1808+252.7169i\\[1 em]x_3 &= -133.1808-252.7169i \end{aligned} $$Explanation
Polynomial $ 2x^3-80x^2-50000000 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
