You can
put this solution on YOUR website! x - square root of x = 0
_
x - Öx = 0
Isolate the radical term
_
x = Öx
Square both sides:
_
(x)2 = (Öx)2
x2 = x
Get 0 on right by subtracting x from both sides
x2 - x = 0
Factor left side
x(x - 1) = 0
Set each factor = 0
x = 0 is its own solution
x - 1 = 0 which has solution x = 1
Now we must always check the answers to radical problems to
make sure they are solutions.
Checking x = 0
_
x - Öx = 0
_
0 - Ö0 = 0
0 = 0
Checking x = 1
_
x - Öx = 0
_
1 - Ö1 = 0
0 = 0
