Answer :

In the given expression


Check weather there is any common factors for all terms;


None;


Regrouping the 1st 2 terms we have,


3ax-6xy = 3x[a-2y] -------eq 1


Regrouping the last 2 terms we have,


8by-4ab = -4b[a-2y] -------eq 2


we have to make common parts in both eq 1 and 2


Combining eq 1 and 2


3ax – 6xy + 8by – 4ab = 3x[a-2y] + [-4b[a-2y] ]


= 3x[a-2y] - 4b[a-2y]


= [3x-4] [a-2y]


Hence the factors of 3ax – 6xy + 8by – 4ab are [3x-4] and [a-2y]
