I have a factoring question; what is 8a^28a30? I've been working on this for a while and I think I understand factoring, but I'm not getting the right answer, which is supposed to be 2(2a5)(2a+3).
Any help would be so appreciated! :)

bobpursley,
factor 2 out (all coefficents are multiples of 2)
2(4a^2 4a15)
Now factor the second part...
2(2a5)(2a+3)
It might take a while to find the factors

Sally,
but, I don't understand how you got the answer in the first place; can you place explain?
