ABSOLUTE EQUALITIES & INEQUALITIESABSOLUTE EQUALITIES & INEQUALITIES

SummarySummary

KeypointsKeypoints NotesNotes

inequalities in algebra that involve algebraic

expressions with absolute value symbols and

inequality symbols( <, >, ≤ or ≥ )

DEFINITION OF ABSOLUTE INEQUALITIES

REMEMBER: INEQUALITIES

Absolute value

inequalities with

negative absolute

values are impossible

to solve. For example

|x + 3 | < 0

cannot be solved

To solve an absolute value inequalities use a number line or formulas.

By using a number line, split the problem into two cases: when the

absolute value is positive and when it is negative and graph the

absolute value inequalities
