I'm going to attempt to ask an educated algebra question. Please forgive a bad translation.

Inequalities and Powers/Roots.

Legend:

() <-Power

[] <-Square Root

Solve:

the square of x is less than 4

x(2)<4

would this translate to

x is less then the positive/negative of the square root of 4.

x<+/>-[4]

or

x<2 and x>-2

[edit1]

-2<x<2

[/edit1]

??????????????????????????

My book doesn't address this type of inequality, and would really like to know this.
