To simplify the given expression, combine like terms by first finding a common denominator.

4(3/√3a) - 9(3/√3a)
= (12/√3a) - (27/√3a)

Now, find a common denominator for the two fractions, which is √3a:

= (12 - 27) / √3a
= -15 / √3a

Therefore, the simplest form of the radical expression is -15 / √3a.
