Simplifying a radical expression by rationalizing the denominator as a binomial

The video tutorial demonstrates how to simplify a radical rational expression by rationalizing the denominator. It explains the necessity of using the conjugate when the denominator is a binomial, leading to the difference of two squares. The process involves multiplying the numerator and denominator by the conjugate, simplifying the expression, and arriving at the final answer. The tutorial concludes with a summary of the steps taken to achieve the simplified expression.
