Answer 1

3*(4b^4-b^2)

Explanation:

you are looking for the greatest number who can be divided by the number(3) and the other number(12) , the greates common factor here is 3

and then take out the 3

so 3*(4b^4-b^2)

Answer 2

9 should be the greatest common factor. (I think) because 3b² =9b

12b⁴=48b
