Solving Quadratic Inequalities | Nov 2024 Grade 11 Math Exam | iCampSA

In this lesson, we solve a tricky inequality question from the November 2024 Mathematics Paper 1. We walk through how to solve (x+1)(4-x) greater than 0 specifically when x is an element of Natural Numbers. Key concepts covered Changing the signs and flipping the inequality [02:57]. Finding critical values (CVs) for the equation [03:29]. Using the Parabola Method (Graph Method) to find the solution set [04:54]. Applying the constraint: Why we only choose 1, 2, and 3 as solutions [10:28]. Lesson timestamps 00:00 - Understanding the problem and constraints 01:25 - Rearranging the equation (Taking out -1) 02:57 - The Golden Rule: Flipping the inequality sign 03:29 - Finding Critical Values 04:54 - Using the Parabola/Graph Method 08:36 - Writing the final solution set 08:48 - Applying the "Natural Numbers" constraint Struggling with Paper 1?
