Algebra Series - Concepts and Formulas
The Discriminant, Quadratic Inequalities and Rational Inequalities (ALG-CF23)

This sheet provides a comprehensive review of all of the most important topics, concepts and formulas covering the discriminant, quadratic inequalities and rational inequalities, explained in detail, with detailed illustrations. Unlike charts and notes, this Concepts and Formulas sheet anticipates and answers questions about how to use the concepts - how to solve problems with them, it doesn't just list facts and formulas.

Topics Covered:

• The Discriminant
• Double roots
• Multiplicity
• The relationship between coefficients and roots
• Equations reducible to quadratic form,
• Quadratic inequalities in standard form
• Sign analysis
• Cut points
• Key numbers
• How to solve a quadratic inequality algebraically
• Rational inequalities
• How to solve rational inequalities
