x(x-1)>0 - Concept problem

by batbond007 » Fri Dec 18, 2009 8:20 am
Given the equation x(x-1)>0 what can be predict about x whether x>1 ,etc...

I have forgotten how we used to solve this. Any quick pointers on how to solve it or tutorials covering the same will be very helpful.

Thanks.

I can think of the following

x not equal to 0 or 1
x and x-1 are both either positive or negative.
