Can you elaborate more on why that confuses you? It seems a is a constant and x is the variable to start off. n also has to be a constant. Just do integration by parts, just like you pointed out in the title. Do you remember how to do integration by parts? I'll start you off, dx will be dv in the Integration by parts equation and the rest will be u.
