I learned how to rationalize a monomial and binomial fraction in Precalc 11 this week. When dealing with fractions the denominator has to be a positive number, not a square root, so we learned how to take away the square root in the denominator.

Here are two step-by-step examples of rationalizing the denominator for a monomial:

Here is a step-by-step example of rationalizing the denominator for a binomial:

Those are two types of questions that we worked on this week. They are very similar to what we have been working on as it uses a lot of the same rules. When solving these types of questions it is important to simplify everything and write out all your steps as it is easy to make a mistake when foiling.
