Learn how to rationalize the denominator with a binomial and radical

The video tutorial explains how to solve a mathematical problem involving rationalizing the denominator of an expression with a square root. The instructor discusses the importance of removing radicals from the denominator and introduces the concept of the difference of two squares. By multiplying by the conjugate, the expression is simplified, eliminating the square root from the denominator. The tutorial concludes with the final simplification of the expression.
