Inequalities

I have a doubt regarding the inequalities.
What is the difference between the two equations mentioned below?
Can u solve for x?

1. x(x^2 -1)=0
2.x(x^2 -1)>0

i'm not sure what you're asking for here. the difference is that one is an equation and one is not (it is an inequality). the equation you should be able to solve outright; the inequality is best solved by turning the greater-than into an equals sign, solving that equation, then noting that these numbers are NOT solutions because they don't satisfy the greater-than condition. so you'll want to investigate the intervals that are punctuated by these non-solutions and see which intervals are solutions. try this and let us know how we can help further..

Thanks Tim, It's clear now.
