When factoring polynomials you are re-writing a an expression as factors, or "un-distributing"
The first thing you always look for when factoring is a greatest common factor. Watch the video below for a review then complete the assignment. There are extra written examples posted as well. Remember you can easily check your answers by re-distributing. The answer key is also posted.

Factor by Grouping.
The greatest common factor can also be a binomial. When a polynomial has 4 or more terms the grouping method can be used. You will still divide out the gcf (common binomial factor) as you did with the problems above.
If there is no common binomial factor then the polynomial can not be factored and is prime and can not be factored.
If there is no common binomial factor then the polynomial can not be factored and is prime and can not be factored.
When a binomial factor is not obvious, you can group together parts of the polynomial and factor a gcf out of each group to see if there is a common binomial factor. In order to group you must have at least 4 terms! Copy the example below then watch the video.
