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
