Adding, Subtracting, Multiplying Radicals

So many rules and so little time. Make it easy and provide all the exponent and radical rules in one place as an easy reference guide. All of the properties come with several examples to show how the rules apply to different problems. 

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...

Sal beautifully explains how to subtract two polynomial expressions with multiple variables. He groups like terms and the distributive property to create a single expression.

This work is radical! The video provides a refresher on radicals. The segment of an extensive basic geometry playlist reminds the class of the the rules for operating and simplifying expressions involving radicals.

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.

Bringing it all together in this video, Sal incorporates the concepts from previous lectures (quadratic formula, multiplying polynomial expressions, radical expressions, exponents). This video would be a great way to end a unit or review...

Rational expressions that are in the form of fractions. Yuk! The teacher demonstrates how to subtract one rational expression from the other when the expressions have a common denominator. Combine like terms and write it in simplest form.
