Answer:

4x(3ax²+5bx+8c)

Step-by-step explanation:

4 is the highest number that fits into all terms of the expression :

So outside the bracket will be 4x :

To find what is inside the bracket we divide each term by 4x  

12ax³÷4x = 3ax²

20bx²÷4x=5bx

32cx÷4x=8c

So our final answer is :

4x(3ax²+5bx+8c)

Hope this helped and have a good day
