6.5 Absolute-Value Equations and Inequalities

What is absolute value? What is an absolute value function? Emerging mathematicians solve equations containing variables inside an absolute value sign.  They graph each function on a coordinate plane and identify the maximum and...

Can you solve an equation graphically? Absolutely! This Algebra II lesson makes the connection between solving an absolute value equation and graphing two functions. Graphing absolute value functions is presented through the process of...

Sal reviews absolute value equations by taking viewers through a careful and deliberate problem-solving process. Those who didn't thoroughly understand absolute value during class will appreciate Sal's steady and straightforward...

Sal demonstrates how to solve an absolute value equation, keeping in mind there are two possible answers.

Combining the skills from the previous videos, particularly inequalities and absolute values, Sal works to solve several new sample problems. He encourages watching the video "over and over," which is good advice for mathematicians of...

The concept of absolute value can be difficult for learners to grasp. Reinforce their understanding of a basic absolute value expression and connect it to solving equations and inequalities. Scholars write two equations/inequalities to...

Intersections become solutions. Scholars watch a video on using a graphing calculator to find the solution to an equation in one variable. While watching the presentation, pupils practice working some of the examples and compare their...

After reading this inequality word problem, young learners might just skip over it and not even make the attempt to solve it. It seems rather complicated. So watch this video as the teacher explains all that needs to be done to solve...

Approach inequalities in a new way with this video! This video gives step-by-step instruction on how to solve a two step inequality and then graph the answer. Learners could use this video as a reference as they do homework, or you might...
