Solving Absolute Value Inequalities:

  1. let k represent a positive real number (k > 0)
  2. To solve |ax + b| > k, solve the following compound inequality:
    • ax + b > k or ax + b < -k
  3. To solve |ax + b| < k, solve the following three-part inequality:
    • -k < ax + b < k
  4. Special Cases of Absolute Value:
    • The absolute value of an expression can't be negative
      • |a| ≥ 0, for all real numbers a
    • The absolute value of an expression can only be 0 if the expression is equal to 0
      • |ax + b| = 0, solve the equation ax + b = 0
