Value of Expression - Practice Problem | CAVEMAN CHANG

For this video series, I will focus on practice problems. Each and every one of these questions, I selected because I feel they truly highlight certain math concepts or they may show up in a standardized test. In order to best use this video, I recommend you pause the video and try to solve the problem before unpausing to see the solution and explanation.

Problem of the Video: What is the value of (x^2-y^2)/(x-y) when x=-7 and y =4?
