Hello. I'm just helping a friend, and it's been so long since I've had this. I don't know how to write a square root sign, so it'ssqrt.

Sqrt x

-------(over)

3 Sqrt x - sqrt y

Is this as simplified as it can be? If it's possible to see the steps, or to be pointed to a resource to see the steps, I know it'll come back to me. Thank you!
