Simplifying Rational Expressions

It doesn't get simpler than this. Scholars first learn to simplify radicals by determining the prime factors of the radicand. The lesson progresses to simplifying radicals involving algebraic expressions in the radicand.

Structure makes everything easier — even math. A helpful resource contains five short problems that require pupils to use the structure of the expressions in order to answer the questions. 

There's a fine line between a numerator and a denominator! Learners find common denominators in order to add and subtract rational expressions. Examples include addition, subtraction, and complex fractions.

Teach class members to work with rational expressions using their knowledge of fractions. The lesson plan starts with a warm-up of rational expressions at four different levels of complexity. The different levels continue throughout...

Cancel that! Young mathematicians see how factoring and canceling can be very beneficial. The presenter works through examples of multiplying two rational expressions where the factors are simplified first. Factoring complex rational...

Extending his asymptotes lesson from the previous video, Sal shows viewers another example of graphing rational functions. This video is shorter than the previous one and could be shown in a single class session.

Use the least common denominator to solve rational equations with variables in the denominators of algebraic fractions. Learners can watch this video to find out how to do just this! An instructor solves 2 problems by finding the least...

A comprehensive video, this resource explains how to solve an equation when you have a variable in the denominator. The lecturer works through 2 different problems that represent 2 situations. From this video, pupils can gain knowledge...

Translate a word problem into a rational equation. This word problem might cause some to pause and ponder, and some to just give up and skip the problem altogether. It does involve some fractions, so watch this video and get a better...

Walk through this tutorial to see exactly how rational expressions are simplified. When you're finished, try the practice problems to see how much you've learned.
