$$14x^3+27x^2-20x = 0$$
Answer
$$ \begin{matrix}x_1 = 0 & x_2 = \dfrac{ 4 }{ 7 } & x_3 = -\dfrac{ 5 }{ 2 } \end{matrix} $$
Explanation
In order to solve $ \color{blue}{ 14x^{3}+27x^{2}-20x = 0 } $, first we need to factor our $ x $.
$$ 14x^{3}+27x^{2}-20x = x \left( 14x^{2}+27x-20 \right) $$$ x = 0 $ is a root of multiplicity $ 1 $.
The remaining roots can be found by solving equation $ 14x^{2}+27x-20 = 0$.
$ 14x^{2}+27x-20 = 0 $ is a quadratic equation.
