Well am not sure.......it would be nice if someone could confirm the answer.

I got....... y = x1/2 + 2/x1/2 + 3

First you need to multiply the denominators so as to obtain one fraction only. You'll get (x - 2)/(2 x3/2)
Then you separate the fraction again to get 1/(2 x1/2) - 1/(x 3/2)
From there its easier to integrate..........try it out.

If you still cannot do it........let me know. :)
