You can put this solution on YOUR website!
In this case, a group of "like" terms are terms that have 'a' to the power of a given number, or don't have 'a' at all.
For example, all terms that have a%5E2 are "like" terms.
So first let's reorder the terms to group first all the ones that have a%5E2, then all the ones that have a, and finally, the ones that don't have a at all:
6a%5E2+%2B+3a%5E2+%2B+4a+%2B+7a+%2B+5+-+2
Using common factor:
%286%2B3%29a%5E2+%2B+%284%2B7%29a+%2B+5+-+2
9a%5E2+%2B+11a+%2B+3
So that's the result after combining like terms.
