The video tutorial introduces a problem involving the sides of a right triangle and uses the Pythagorean theorem to find the integer value of the longest side. It explains the theorem's basics, demonstrates solving two example problems, and finally solves the initial problem using the quadratic formula. The tutorial emphasizes understanding the relationship between the sides of a right triangle and applying mathematical formulas to find missing values.
