Factor the GCF: 12a^3b + 8a^2b^2 - 20 ab^3

GCF is 4ab

And the expression will be: 4ab (3a^2+2ab-5b^2)

Step-by-step explanation:

Factor the GCF:

12a^3b + 8a^2b^2-20 ab^3

We need to find the common terms that are common in each of the term given above

12,8 and 2 are all divisible by 4

a is common in all terms and b is also common in all terms,

So, GCF is 4ab

Taking 4ab common

12a^3b + 8a^2b^2-20 ab^3=4ab (3a^2+2ab-5b^2)
