Question

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

Answer 1

GCF is 4ab

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

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)
