Simplify the expression. (2+i)(6+8i)

(2+i)(6+8i)
{2*6=12.2*8i=16i.i*6=6i.i*8i=8i^2}
12+16i+6i+8i^2
12+22i+8i^2
answer=12+22i+8i^2

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
