1) 1/(Square Root of x) - 1 / x - 1

So I multiply both top and bottom by 1/(Square Root of x) + 1 , right? But I don't know what that equals, I just don't know how to multiply them...

2) x(Square Root of x) - 8 / x - 4

Same thing...maybe if I get help on 1 I can get this one.

More questions to come I'm sure...
