The video tutorial explains how to factor a given expression to identify removable and non-removable discontinuities. It begins with an introduction to the problem, emphasizing the need for factoring. The instructor demonstrates factoring the numerator and denominator, identifying the difference of squares and the factors of the denominator. The tutorial then focuses on identifying discontinuities, explaining the concept of removable and non-removable discontinuities, and concludes with a brief mention of further examples.

At which value of X does the removable discontinuity occur?

What is the significance of the value X equals -2 in the context of the problem?
