A) fund the exact value of x^2
B) hence, determine the simplified form of x Answer by Edwin McCravy(20054) (Show Source): You can put this solution on YOUR website! x=sqrt(3+2sqrt(2)) + sqrt(3-2sqrt(2))
A) fund the exact value of x^2
B) hence, determine the simplified form of x
To make things easier, let
and
Then
Now since
, we'll need AČ, BČ, and AB
Substituting in
,
,
,
,
But x cannot be negative.
