Well look at what both terms have in common..

what numbers go into both 12 and 16 evenly? Well all the answer choices involve 4...so yes 4 is a good one....so if you factor out a 4 from that equation you get

4(3a^4 + 4a^6)

Now what else do we have? Both terms have 'a's in them...and it look like they both have at least a^4 in them...so lets factor that out

4a^4(3 + 4a^2)
