The answer is 3(3x-4y)^2

Explanation:

In the given expression we can see that the coefficients of the polynomials are 48,72 and 27 these numbers are divisible by 3
When you take 3 common from these numbers this expression becomes:
3(9x^2-24xy+16y^2)
and when we factorise 9x^2-24xy+16y^2 we get (3x-4y)^2
so finally we get 3(3x-4y)^2 as our answer.
