Expand the expression: $\large(\frac{2}{x} - \frac{x}{2})$$^5$

Question

$\begin{array}{1 1} \large\frac{32}{x^5} - \large\frac{40}{x^3} + \large\frac{20}{x} -5x+\large\frac{5x}{8}-\large\frac{x^5}{32} \\ \large\frac{32}{x^5} + \large\frac{40}{x^3} - \large\frac{20}{x} -5x+\large\frac{5x}{8}-\large\frac{x^5}{32} \\ \large\frac{32}{x^5} - \large\frac{40}{x^3} + \large\frac{20}{x} +5x-\large\frac{5x}{8}+\large\frac{x^5}{32} \\ 32 - \large\frac{40}{x^3} - \large\frac{20}{x} -5x+\large\frac{5x}{8}-\large\frac{x^5}{32} \end{array} $
