To solve the inequality , we start by rewriting it in terms of a square root. This leads us to . This means that any value of within this open interval will satisfy the original inequality. Picture it like a warm hug from -13 to 13, where you’re free to roam but don’t go beyond those bounds!

When grappling with inequalities, it’s common to overlook the implications of squaring terms. Mistakes often arise when students forget the open interval at the roots, or when they accidentally switch signs when multiplying or dividing by negative numbers. Always remember: the direction of the inequality changes when you multiply or divide both sides by a negative value!
