solve the given equation for x

(x-9)^(1/2)=36/(x-9)^(1/2) - (x)^(1/2)

Sorry I didnt write it in radical form, wasnt sure how. btw the -(x)^(1/2) is in the numerator. the answer in the back of the book is 25. Half way thru i got x + (x)^(1/2) - 45 = 0 and then substituted y = (x)^(1/2) and y^2=x for the values. But my end results didnt seem to be right. Sorry if this is cluttered.
