I'm assuming that it's supposed to be: 8a%5E3-2a%5E2-12a%2B3


8a%5E3-2a%5E2-12a%2B3 Start with the given expression


%288a%5E3-2a%5E2%29%2B%28-12a%2B3%29 Group like terms


2a%5E2%284a-1%29%2B%28-12a%2B3%29 Factor out the GCF 2a%5E2 from the first group.


2a%5E2%284a-1%29-3%284a-1%29 Factor out the GCF -3 from the second group.


%282a%5E2-3%29%284a-1%29 Factor out 4a-1


So 8a%5E3-2a%5E2-12a%2B3=%282a%5E2-3%29%284a-1%29
