Graphing Quadratic Inequalities using a Short-Cut Method

This video reviews graphing Quadratics and introduces a Short-Cut Method for graphing Quadratic Inequalities. Two examples are worked out with graph paper and 2 more examples are "sketched" to emphasize "how" to shade. ******************************************* Math Tutorials on this channel are targeted at college-level mathematics courses including calculus, pre-calculus, college algebra, trigonometry, probability theory, TI-84 tutorials, introductory college algebra topics, and remedial math topics from algebra 1 and 2 for the struggling college adult (age 18 and older). ******************************************* Don’t forget guys, if you like this video please “Like” and “Share” it with your friends to show your support - it really helps me out! ******************************************* For More Math Tutorial Videos, check out all of my Playlists: TI-84 Calculator Videos: http://bit.ly/2novtib Calculus Videos: http://bit.ly/2nozSlf AP Calculus AB Test Tips Videos: http://bit.ly/2noq7DM STEM Project in Calculus: http://bit.ly/2noq0bq Pre-Calculus Videos: http://bit.ly/2noi0H8 Trigonometry Videos: http://bit.ly/2nojaCK Algebra Videos: http://bit.ly/2noyVtr Algebra 2 Videos: http://bit.ly/2nopGJK M104 at IUK Videos: http://bit.ly/2notD0Z M105 at IUK Videos: http://bit.ly/2nosA1a Extremely Nerdy Math Jokes: http://bit.ly/2nopAle Fun Things to do on the TI-84: http://bit.ly/2nopVVa Math Tricks: http://bit.ly/2nopsCa Classroom Teaching Ideas: http://bit.ly/2nouxKO ******************************************* Be sure to check out Cole’s World of Mathematics around the web!
