Question 189394: Hello. I'm practicing for an exam and I need some help with the following problem.
Solve the equation:
2 + squareroot(2-x) = x
thanks! Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! 2 + squareroot(2-x) = x
------------------
Step 1 - isolate the radical.
Then square both sides. This eliminates the radical.
(x-1)*(x-2) = 0
x = 1
x = 2
----------
2 works.
The 1 is an extraneous solution, ignore it.
