You can put this solution on YOUR website! Very good idea
.
-[ 5-sqrt2]
.
Lets review absolute value, answer is distance to zero therefore always positive
.
[2] = +2,,,,,,,[ -2] = +2
.
[x] = +2, ,,, x= +2,,,,,,and x=-2,,,,,same as above
.
-[ 5-sqrt2]
.
-{ +(5-sqrt2)},,,,,,,and -{ -(5-sqrt2) }
.
-5 +sqrt2 ,,,,,,,,,,,and +5 -sqrt2
.

Very confusing with the minus out front. It has nothing to do with absolute value, it just reverses sign at end. It is always good to practice, until you are comfortable. Good Luck
