A short demonstration of multiplying and then reducing the result when presented with the product of two radical expressions.


Just a quick couple of examples, one explaining the relationship between squaring and square rooting and one that just shows how to multiply two radical expressions that need no reduction.


This includesradicals that contain variable factors, but continues the simplification of various terms in a sum or difference so that possible like terms can be added orsubtracted.


A quick justification of dividing fractions by multiplying by the reciprocal of the second fraction in the division followed by an example that involves reducing the common factors in the numerator…


Starts with cautiioning against multiplying the factors back together and describes the zero product property to justify this warning. Then shows how to continue from the factored form to separate…


This demo discusses how to set up two equations to solve the situation described, and then choose the best method to use to solve for each of the variables.


This talks about why we need two equations to solve for two unknown values, and then demonstrates how to add two equations together to eliminate one varaible and solve for the other one, then find…


Some discussion of vocabulary combined with writing a simple expression from a verbal description.


This describes the process of solving for a particular variable in terms of other variables in an equation. There is a need to go further to combine like terms before it is complete.


Describes how to rearrange a simple formula with several variables so that a different and particular one is isolated.


A somewhat fancierversion of seveal solving equation versions that should help solidify the process in your mind.


A more complicated version of solving an equation. It specifically addresses dealing with two variable terms on the same side of the equals sigh.


A short and simple demo about adding like variable terns that are together on one side of the equals sign in an equation.


This demonstrates how to write the function that includes the initial amount multiplied by the percent remaining or the initial amount multiplied by one plus the percent increase, with either being…


Multiplication of two radicals by pairing all numbers after prime factorization and taking half of all even exponents with variables as a base.


Two examples of simplifying expressions under a square root symbol to "liberate" as many factors as possible
