Learn how to find the holes of a rational function removable discontinuities

The video tutorial explains the concept of discontinuity at X=5, emphasizing that X cannot equal 5. The teacher guides through the factoring process, focusing on finding two numbers that multiply to -10 and add to -3. The expression X-5 * X+2 is simplified, and the discontinuity is identified as a removable hole. The session concludes with a task for students to apply the learned concepts.
