Dividing by a binomial with a radical expression

The video tutorial explains how to simplify a radical expression by dividing it using the conjugate. It begins with an introduction to the problem of dividing by an irrational number and proceeds to demonstrate the use of the conjugate to simplify the expression. The tutorial covers the multiplication of radicals and binomials, highlighting the importance of the difference of two squares in simplifying the expression. The final section provides a step-by-step simplification of the expression, resulting in a simplified form.
