1/ sqroot(x) - 1/2 / x-4

I first simplified by multiplying by 2sqroot(x) = 2-sqroot(x) / (x-4) (2sqroot(x)) than i was going to rationalize the numerator by multiplying by 2+ sqroot(x) but that seemed too complicated.

Where did i go wrong?

I dont know how to, but well i suppose its the same but its (1/rootx - 1/2 ) / (x-4)
