Algebra 15 – Modulus Equations
You’ll learn
- Interpret |x| as a size or distance that can never be negative
- Solve modulus equations by splitting into ± cases or by squaring both sides
- Always square both sides when a modulus meets an inequality
- Solve |f(x)| = |g(x)| by squaring to remove both moduli at once
