Adding ratioinal expressions with quadratic denominators requires factoring each denominator so that the LCD can be determined. Then each fraction is exapanded by multiplying the tops and the…


This example shows how to factor each denominator and then determine which of these factors are needed to create the least common denominator (LCD). Then the fractions are expanded by multiplying…


This example shows how to add fractions with different denominators by adjusting one of the fractions so that they have a common denominator.


Each denominator is factored and then any common factor is used only once and all other unique factors complete the LCD


A demonstration of how factoring is used to discover the minumum number of factors that need to be combined to find the smallest denominator that can be used as the LCD of the two given fractions.


This demonstrates how to convert negative exponents in a complex fraction to the reciprocal positive exponents and then use the LCD of all fractions to simplify.


Shows how to simplify a large fractions with fractioins embedded in it. The simplest way involves multiplying all small fractions by their least common denominator so the individual denominators…


Shows how to use the given factors of two different denominators and find the LCD then adjust the fractions so they can be added


Factoring quadratics to find the LCD of two fractions in algebra


This shows how to find the least common denominator of two fractions, nothing more.


Shows how to create the simplest expression both of the given ones divide into.
