Squaring an expression is the same as multiplying the expression itself twice.


Using the FOIL method we get


Simplify by combining like terms.

`sqrt3^2 -4sqrt3sqrt2+4sqrt2^2`

Raising a square root to the second power results in just the expression under the radicand.




``The solution is  `11-4sqrt6`
