"The neat thing about completing the square is that it will always work," Sal explains, "no matter how crazy the problem is." A basic overview of how to complete the square, this video provides a good background for both beginning and...

You know how to find absolute values and you know how to solve inequalities — but what happens when these two concepts are in the same problem? A YouTube video first reviews absolute values and moves on to solving absolute value...

Solving a simple absolute value equation.

This tutorial explains how to solve a variety of equations, from simple to complex, and gives examples and solutions. Students are asked to solve for x before looking at a solution.

Why are you so negative? Just take me for my absolute value! A video gives the definition of absolute value as its relationship to a number line before the presenter provides an explanation of how to interpret situations as absolute value.
