Inequalities involving powers - Not able to solve

Consider the equation x^2 > x , simplifying it as below
=> x^2-x>0
=> x(x-1)>0
so x>0 or x>1.

Just curious values for x<0 is also valid for the above equation but when I solve mathematically I don't seem to get this as an option
Can you plase let me know where I am going wrong.

Thanks
