Here are five related questions for further exploration:
- What happens when the absolute value is equal to zero?
- How do you graph inequalities involving absolute values?
- Can you solve an absolute value equation with a variable on both sides?
- How does the solution change when you have nested absolute values?
- What is the geometric interpretation of absolute value on the number line?
Tip: When solving absolute value equations, always break the problem into two cases—positive and negative—and solve both separately!
