2.2Solve Absolute Value Equations and Inequalities Math Midterm: March 11
Vocabulary • Extraneous Solution • An apparent solution that must be rejected because it does not satisfy the original equation a FAKE solution
Example 1: • Solve |x – 3| = 6 Make sure to check for FAKE solutions
Checkpoint: Make sure to check for FAKE solutions • Solve the equation. • |x| = 5 • |x – 5| = 2
Example 2: • Solve |4x + 10| = 6x Make sure to check for FAKE solutions
Checkpoint: Make sure to check for FAKE solutions • Solve the equation: • |2x + 5| = 11 • |3x + 18| = 6x
2.2Continued Math Midterm: March 11
Example 3: greatOR • Solve |2x + 5| > 3
Example 4: less thAND • Solve |x – 1.5| < 4.5
Checkpoint: • Solve the inequality. • |x – 2| > 7 • |4x – 1| < 9
