Solving equation for wifi password.

No need to know much of calculus,

$$\frac{u((u^2+5)-3)}{\sqrt{u^2+5}}=u(u^2+5)^{1/2}-3u(u^2+5)^{-1/2}.$$

My bet is that the "Pasword" is "one" or "1", assuming a typo ($-5$ instead of $+5$; also missing $du$), and assuming that the integration constants can be ignored.
