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


Demonstrates how to remove a common factor that not just a single number or variable, but a binomial i. e. a twoterm expression.


Demonstrates how factor a greatest common factor (GCF) from a polynomial.


Shows how to factor the greatest common factor from a simple linear binomial


This demonstrates why symthetic division works when dividing by a simple binomial as in x + a or x  a. Then it shows how to fill in the answers for this type of question.


Shows how to distribute a division like you do with multiplication when there is one term being distributed.


Demonstrates what happens when the F.O.I.L. method is applied to multiply two binomails of the form (a + b) (a  b). It's special circumstance that allows a short cut.


Demonstrates how to multiply a single term by an expression with more than one term but containied in parentheses. using distribution.


The key to getting this type of question is distributing any minus sign on the outside of the parentheses to each term on the inside thereby changing all of the i nner signs to their opposite


Another example of simplifying a fraction in parentheses raised to a power


Using the quotient rule, we can eliminate the negeatiev exponent rigiht awa and then applly the "power rule".


A short example of how to deal with a fraction raised to a negative power.


Explains the reason why exponents are multiplied in a power of a power situation, then simplifies two examples.


Reminder of the negative exponent rule, then transforming a couple of numerical expressions with negative numbers as bases as well as exponents.


Negative powers of 10 means that they are very small fractions.


A quick example of reducing a fraction by dividing matching factors on the top and bottom.
