You can put this solution on YOUR website!
2a+6/(a^2+6a+9)+1/a+3

Assume you mean:
%28%282a%2B6%29%29%2F%28%282a%5E2%2B6a%2B9%29%29 + 1%2F%28%28a%2B3%29%29

Factoring won't help here.
1. Put the two fractions over a common denominator,
2. FOIL (2a+6)(a+3)
3. Combine like terms:
= = %28%284a%5E2+%2B+18a+%2B+27%29%29%2F%28%282a%5E2%2B6a%2B9%29%28a%2B3%29%29

That's about all you can do with it. Nothing will factor.
