In this example, the multiplication of two fourthroots of numbers is shown and the reduction of the result


A subtraction of fractionso where the denominators have no factors in common so we simpllly multiply the two together to create the LCD. Then both fractions are adjusted by multiplying each…


This shows how to determine a common denominator when the denominators share at least one factor. A numerical version is included for more understanding, and the rational expressions are added and…


An example that is easy to combine with subtraction, in this case, because the two fractions have common denominators. However, be aware that there may be a way to simplifying the answer further. …


A short reminder of how to reduce first and then multiply two numerical fractions. Then we apply the same priciples to reducing like factors in an example with more than one variable and numerical…


Expands each monomial as a list of all of its prime factors, then showing those that both lists have in common to develope the GCF.


A demo of this topic where I stack the l ike terms in columns as a perform the distributions connecting each term of the first polynomial to each term in the other.


This shows how to represent the two unknowns using their given relationship so that a linear equation can be written using one variable. Then that equation is solved to answer the question


Shows how to interpret a verbal description into an mathematical equation.


A quick statement of the property followed by two examples of its use.


A short demo involving subtracting whole numbers from both sides of an equation. There are two examples.


Two quick demonstratoins of a rational expression containing radicals being ratioinalized by multiplication of a form of one to transform a radical in the denominantor to a whole number.


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)


Demonstrations that emphasize the fact that a fraction bar acts like parentheses in that the each part of the fraction must be factored so that there is a product of factors on both top and bottomof…


A demonstration of squaring a binomial with radical terms and then a second example showing how conjugate binomials can be multiplied.
