Simplifying Rational Expressions (Old Video)

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.

Rational expressions are just fancy fractions! Pupils apply fractions concepts to rational expressions. They find equivalent expressions by simplifying rational expressions using factoring. They include limits to the domain of the...

Linear or not linear — that is the question. The lesson plan has class members translate descriptions into algebraic expressions. They take the written expressions and determine whether they are linear or nonlinear based upon the...

Many times budding algebrists are fine when plugging specific numbers into expressions, but less certain when the range of acceptable values is undetermined. This detailed presentation helps the class move from the point value to...

A brief presentation with laser-like focus, this video talks young mathematicians through the mechanics of simplifying algebraic fractions by factoring trinomials. While the factoring itself is assumed to be a mastered skill, the...

It only takes the denominator to be zero to make an expression undefined. A video resource makes the connection of undefined fractions to rational expressions. It points out that to determine when a rational expression is...

A monomial raised to a power needs to be multiplied. No problem. Use the product of a power rule and the power of a power rule too. Now all that needs to be done is to simplify the product.

Young writers design and publish a newsletter with articles that demonstrate knowledge of mathematical concepts. They explain mathematical procedures and basic operations in a news article format. Next, they compile several articles to...

Demonstrate the order of operations and the way to evaluate numerical expressions containing grouping symbols and exponents. An instructive video introduces learners to the mnemonic PEMDAS, which is a great way for them to...

If you know how to use the distributive property and you know how to combine like terms, then you can simplify this expression.
