Find roots of polynomial $$ p(x) = 3x^3-2x^2-150 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 3.9202\\[1 em]x_2 &= -1.6268+3.1793i\\[1 em]x_3 &= -1.6268-3.1793i \end{aligned} $$Explanation
Polynomial $ 3x^3-2x^2-150 $ has no rational roots that can be found using Rational Root Test, so the roots were found using qubic formulas.
