%28sqrt%286%29+%2B+1%29%283%2Asqrt%286%29+%2B+1%29
Just use FOIL (First, Outside, Inside, Last):
sqrt%286%29%2A3sqrt%286%29+%2B+sqrt%286%29%2A1+%2B+1%2A3%2Asqrt%286%29+%2B+1%2A1%29
Simplifying we get:
3%2A%28sqrt%286%29%29%5E2+%2B+sqrt%286%29+%2B+3sqrt%286%29+%2B+1
3%2A6+%2B+4sqrt%286%29+%2B+1
18+%2B+4sqrt%286%29+%2B+1
19+%2B+4sqrt%286%29
