How to solve (x+y)^1/2 - x^1/2?

Hi...

I need help...

How can you solve (x+y)^1/2 - x^1/2

I need it for a physics problem...

The problem is actually:

Delta v = ((ku^2/m)+2gh)^1/2 - (ku^2/m)^1/2

Can you help me please

Update:

I need to substitue delta V in an equation..

The equation currently is:

X=Delta v.(u/g).cos alpha.(k/m)^1/2

Update 2:

@Rafaelle...

I used your equation but im still stuck..

I now have:

2gh/(√(ku^2/m 2gh) √(ku^2/m))

So i'm still stuck
