Question 535991
Yes you would combine like terms. This problem is confusing because it's turned around a different way than what you are used to seeing.
The common factors in this problem are 6 and x^3, both of these will factor it to its lowest form. 
For example:
6x^3(x+2)= 6x^4+12x^3, which is the same thing as 12x^3+6x^4 just written differently.
