x= 0 is an obvious answer

---------------------------------

If x>0

, both terms positive hence x>3 is an answer

One of the term is negative hence

its not an answer

-----------------------------------

When x<0 , sign of inequality changes as , you can remember that we canceled an x initially

, is an answer

is similarly not an answer - Mar 24th 2009, 09:29 AMpankaj
