How to Solve Quadratic Inequalities Using Number Lines
The Organic Chemistry TutorThis video provides a comprehensive tutorial on solving quadratic inequalities using algebraic methods and number line analysis. The instructor guides viewers through three distinct examples, progressing from standard quadratic inequalities to those involving perfect square trinomials and leading coefficients greater than one. The central method involves manipulating the inequality to compare a quadratic expression to zero, factoring the expression to find critical values (roots), and using a number line to test intervals for positive or negative values.
