I suppose this is probably pretty easy for people in the know

Recently I've been using Wolfram Alpha, which is an amazing tool, I mainly like it for showing the steps in calculus, however it doesn't want to give the steps for differential equations

Anyway, the question is as follows...

Now I know it's separable so I've put the square root bit under the y'

then I integrated both sides separately

leaving me with

However wolfram alpha is giving a rather more complicated answer of

So is WA wrong, or if it isn't, what steps have been taken to get to that answer?
