Alright, first thing, lets make this a simpler problem
When solving this we distribute
Using this formula, lets distribute the first expression
When you have a root and a square, they cancel one another and leave the number that is in the root. So, therefore, the first number is just 6
When multiplying roots, they can move under one root.
Factor the root
Take the pairs that are under the root, to the outside, but when you do this, one of the pair disappears.
Multiply what is left under the root
DONE
