03 Solving Quadratic Inequalities

Master quadratic inequalities with this clear, step-by-step tutorial designed for high school Mathematics learners! In this lesson, you will learn how to solve quadratic inequalities by finding critical values and determining the final solution set using both the graph method and the table (sign diagram) method. We break down the process in a simple and exam-focused way, helping you build confidence for IEB and CAPS assessments. You’ll also explore common mistakes learners make and how to avoid them when interpreting inequality signs and solution intervals. In this video, you will learn: How to find critical values by solving quadratic equations How to use a number line (table method) to test intervals How to sketch and interpret graphs of quadratic functions How to write final answers in interval notation or inequality form This is a must-watch lesson if you want to improve your algebra skills and perform better in exams!
