Class 11 Maths Linear Inequalities Types of Inequalities

Types of Inequalities:

  • Numerical inequalities: Relationship between numbers. E.g. 3 < 5
  • Literal or variable inequalities: Relationship between variables or variable & number.  g. x < 5
  • Double Inequalities: Relationship from two side. E.g. 2 <x < 5
  • Strict inequalities: An inequality that uses the symbols < or >. The symbols ≤ and ≥ are not used. g. x < 5; 3<5
  • Slack inequalities. An inequality that uses the symbols ≤ or ≥ E.g. x ≤ 5
  • Linear inequalities in one variable: An inequality which involves a linear function in one variable E.g. x < 5;
  • Linear inequalities in two variables: An inequality which involves a linear function in two variable E.g. 3x + 2y < 5;
  • Quadratic inequalities: An inequality which involves a quadratic function .E.g. x2 + 2x ≤ 5
