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