You can put this solution on YOUR website! Because the square of a negative number is a positive number, we know x >= 0.
We are looking for all x such that
Dividing both sides by x (with the requirement that x<>0) gives , ,
So we have narrowed it down to 0 <= x < 1.
And since , we can eliminate 0.
So we can say for all 0 < x < 1.
