Not sure what you have
x-3sqrt%28x%29-54=0
?
x-3sqrt%28x-54%29=0
?

"yes"----------------
No! WHICH ONE?


--------------------------------------
x-3sqrt%28x%29-54=0
--------------------------------------

To begin, x-54=3sqrt%28x%29
%28x-54%29%5E2=9x
x%5E2-108x%2B54%5E2-9x=0
x%5E2-117x%2B2916=0

Using general solution for quadratic equation,
x=%28117%2B-+45%29%2F2

highlight%28x=36%29 or highlight%28x=81%29
