The domain of the original expression is all real numbers except for the values of x and y that make the denominator equal to zero.
So, the domain of the original expression is x ≠ -5y.
So, the domain of the original expression is x ≠ -5y.

To find the domain of the original expression, we need to consider the values of a and b that make the denominator equal to zero.
The denominator of the expression is a^2 - 3ab. Setting it equal to zero gives us:
a^2 - 3ab = 0
Factoring out a common factor of a, we get:
a(a - 3b) = 0
This equation will be satisfied if either a = 0 or (a - 3b) = 0.
Therefore, the domain of the original expression is:
a ≠ 0 and a ≠ 3b.
