If x - SQRT(x) = 0 Then x = SQRT(x) and x2 = x
Then x2 - x = 0 or x(x-1) = 0 so the roots are x = 0 and 1
If x - SQRT(x) = 0 Then x = SQRT(x) and x2 = x
Then x2 - x = 0 or x(x-1) = 0 so the roots are x = 0 and 1

x - √x = 0
√x = x
Squaring both sides, we get x = x2.
So, x2 - x = 0
x(x - 1) = 0
x = 0 or 1
