Hi, there--
Remember that the letter i represents the complex number, the square root of -1. You solve this problem by using the distributive property. We have a two-term expression multiplied by another two-term expression. If you remember "FOIL" from earlier algebra classes, this is a similar process.
.
Multiply each term in the first expression by each of the terms in the second expression. You will then have one 4-term expression.

.
Now simplify and combine any like terms [Note:(-i)(i)=1].

.
Now you can factor sqrt(6) out of the first two terms, and simplify.

.
Hope this helps! Please email me if you are confused about any of my steps.
