Quadratic Inequalities

The video tutorial covers solving quadratic inequalities both algebraically and graphically. It begins with an introduction to quadratic inequalities, explaining the concept and methods for solving them. The tutorial then delves into algebraic solutions, providing step-by-step instructions for converting inequalities into equations, finding roots, and determining solution sets. The latter part of the video focuses on graphical solutions, illustrating how to sketch parabolas and identify solution regions based on the graph's position relative to the x-axis.
