Homework Help: Math

Posted by Ashley on Friday, June 14, 2013 at 4:41am.

Please please help!!!!!

Solve the inequality and write the solution set in interval notation
4x^3 -6x^2<0
2x^2 (2x-3)<0

2x-3<0
x= 3/2

Now I'm not sure about this
2x^2<0
x^2<1/2
sq root of x^2<sq root of 1/2
x=.7071
Right?

When I plug it in the calculator it says
X=0

How?
