This video explains the situation we are trying to minimize or maximize and the role of the input and output variables. Then the process of finding the location and value of the requested amount is…


Shows that the division of sqaure roots is equivalent to the square root of a fraction, and then simplifies the fraction to complete the task.


A brief informal reasoning of why any division can be changed to a multiplication by reciprocating the second number or fraction, i. e. the number going into the other number. Then an example of…


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…


This states the Multiplicative Propery of Inequality, then demonstates how it works with two examples.


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


An examplel of how to rearrange a formula to better suit its particular purpose. Often we need to do this because it is easier to rearrange it once instead of having to solve for a variable each…


A simpler version of an equation that needs distribution across a set of parenthese as the first step to solving for the variable


A review of the sign rules for multiplication and three examples to demonstrate these.


Shows how square rooting is the opposite of squariing


This demonstrates creating a multiplication in the numerator of a rational expression that will allow the expression to be reduced by dividing like factors to simply one


This demonstrates the squaring of a binomial with radical terms and the multiplication of conjugates (sum and differences of the same terms)


This video shows how to multiplly the top and bottom of a square root of a fraction to get the result of a rational number in the denominator.


Demonstrates using factoring skills to separate and identify all of the necessary factors that make the LCD (Least common denominator) that can be used as a multiplier through a rational equation to…


Shows how to find a common denominator to use as a multiplier for each term in a rational equation (an equation with fractions) to then eliminate the denotminators and the result will be a more…


Demonstrates how to reduce a complex fraction when the technique of factoring a greatest common factor (GCF) is needed.
