Answer:

$x>\frac{1}{2} \\x$

Step-by-step explanation:

If we solve for 'x' variable, its recommended to multiply 'x' variable in both sides of inequality:

we have $\frac{1}{4}< x^{2} \\$

This is a quadratic equation, two answer are going to be obtained from here.

since $\sqrt{x^{2} } = |x|$

Applying square roots to both sides of inequality sign we wil have the following

$\sqrt{\frac{1}{4} } < \sqrt{x^{2} }$

This leaves to the following

$\frac{1}{4}$

remember that $|x|= +/ - x$

$x>\frac{1}{2} \\x$
