## Homework Statement

Integrate: 3sec3x(3sec3x+2tan3x)dx

## The Attempt at a Solution

Ok I just multiplied out and obviously got the integrals of both to be tan3x +c and 6sec3x+c
My question is does that make my final answer tan3x+6sec3x +c or +2c?

I swear this is the last integration question I will ask. For awhile.
