Find the vertical asymptotes (if any) of the graph of the function. (Enter each asymptote as a complete equation. Separate multiple equations with commas. If there is more than one asymptote, your final answer should appear as a comma-separated list of equations. Use n as an arbitrary integer if necessary. If an answer does not exist, enter DNE.)
g(x) = (9+x)/(x**2(5-x))
