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 two-term 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.
