How do you solve quadratic inequalities? These are inequalities where your quadratic is greater than or less than 0, not greater than or less than y. Those are graphing problems that will be in another video :-)
This video shows you in visual / graphical form what's happening when you're solving a quadratic inequality that is greater than or less than zero (or greater than or equal to or less than or equal to zero). I also walk you through an example of how to factor and then find the final answer mathematically without the use of a graph. I also show you the answer as an inequality and also using interval notation.
If you would like me to do a video on interval notation, please leave a comment below.
