Kelas 9 - Memecahkan Pertidaksamaan Kuadrat (Matematika Tagalog/Filipino)
Hi guys! This video discusses how to solve quadratic inequalities or those inequalities involving 2 as the highest possible exponent on a single variable, say x. When solving quadratic inequalities, we must always make the right side of inequality zero. Then, we will find the so called critical numbers which are the numbers that can make the formed quadratic function zero or undefined. Then these critical numbers may dividet the whole number line into three regions(for the case of quadratic inequalities) Then we can select any number within each interval as test point to validate that each region will satisfy the given inequality. We solve different examples to illustrate the process of finding the solution set for quadratic inequalities. Happy learning and enjoy watching! #math #tagalog #algebra #solvingquadraticinequalities
