Simplifies a complex fraction by distributing the LCD of each small fraction across the top and the bottom so that all small fractions can be swept away.
|
|
|
A complex fraction is multiplied through on the top and the bottom by the common denominator of all smaller fractions, eliminating the denominators of those smaller fractions.

|
This shows both a subtraction and an addition example for finding the sum and difference of two trinomials.

|
|
This shows how to factor the numerator and denominator of a fraction in algebra so that we can reduce the same factors ono the top and the bottom because they divide to one.
|
|
|
Shows how to find out what values are not defined for a rational function. This ability will be needed when solving rational equations because you may come up with a value that is not valid when…
