Differentiating y = x(x-1)^1/2

[quantumdude]

Good Lord. I had locked this thread, thinking that it had run its course and that any future posts would just be more bickering from aek. But I can see now that this thread is not over, because...

$$\frac{2(x+1)+x\sqrt{x+1}}{2(x+1)}$$

This answer is wrong.

It took my 4 days without a proper answer on PhysicsForum.com, however, it took less than 12 hours on a different forum which i refuse you people to join. Your all geniuses, CLAP FOR THE HANDICAPS.

No, the correct answer was supplied by Dexter and Hurkyl, in posts 25 and 26, respectively.

My suggestion:

1. Ditch that other forum immediately.
2. Show your work from now on.

and oh yes:

3. Can the attitude.
