Question
$$x^5-2x^4 = 0$$
Answer
$$ \begin{matrix}x_1 = 0 & x_2 = 2 \\[1 em] \end{matrix} $$
Explanation
In order to solve $ \color{blue}{ x^{5}-2x^{4} = 0 } $, first we need to factor our $ x^4 $.
$$ x^{5}-2x^{4} = x^4 \left( x-2 \right) $$$ x = 0 $ is a root of multiplicity $ 4 $.
The second root can be found by solving equation $ x-2 = 0$.
