This video focuses on a series of problems involving exponent properties. Sal demonstrates rational expressions, simplifying fractions, and manipulating algebraic equations using exponents and division.

Provide your algebra class with some review of rational expressions in this video. Sal uses several sample problems to demonstrate the process, and his explanations are clear and easy to follow.

Finishing up his short series on rational expressions, Sal reviews the concept with another example. Those who have a hard time with rational expressions will appreciate the clarity with which Sal explains his process and methodology.

Here is a quick look at how one could simplify a monomial expression involving division. Sal works on a problem and briefly explains his process. Great as a concept review.

Divide and conquer factoring. Learners see how dividing polynomials is similar to long division of numbers. Pupils learn how to use long division of polynomials to help find factors of higher degree polynomials. They then use their...

Combine a video with the lesson on combining rational expressions. Young mathematicians first review how to add and subtract rational numbers. They then learn how to apply the same reasoning to add and subtract rational expressions by...

It doesn't need to be complex. The second of five installments in the Algebra II - Rational Expressions unit focuses on multiplying and dividing rational expressions. Scholars learn how to perform these operations as well as how to...

Don't be excluded from learning about rational expressions. Viewers of an educational video first find values that are excluded from the domain of rational expressions. They then see how to simplify rational expressions by factoring the...

Do the keep, change, flip dance. The resource shows that the division of algebraic fractions follows the same rules as dividing numerical fractions. Pupils understand that if they can multiply rational expressions, they can divide...

Make the complicated look relatively simple. The video shows how multiplication of algebraic fractions is easier when they factor the numerators and denominators. Pupils see which factors will cancel, or divide out, easier when writing...

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...

A rational expression is a fraction where the denominator and/or the numerator is a polynomial. The resource presents rational expressions and how to add and subtract them. Additionally, the video connects the addition and subtraction of...

Complex fractions are fractions divided by fractions—complicated, right? The video introduces the class to algebraic complex fractions. With the introduction to variables in the denominator, it is important make sure the denominator is...

Demonstrate the steps of dividing rational expressions with an instructional video that works through two division problems. Numerators and denominators are quadratic trinomials and include several common factors.

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...

Let's be rational about it. An instructive resource provides the definition of rational expressions and rational functions. Examples provide an explanation on how to determine excluded values from the domain. The resource continues...

Long division is back and better than ever! A math video looks at the process of dividing rational expressions using the long division algorithm. The instructor works through the steps of dividing polynomials that result in a...
