This area contains help in solving polynomial equations by factoring.

You will find several levels (intermediate and college) of help in solving polynomial equations by factoring. There will be some overlapping between the levels.  If a topic has tutorials in more than one level, try going under the highest level first.  If that is too hard for you, go to the tutorials of the next level down, if available.  If that is too hard for you, go to the tutorials of the next level down, if available. 

Once you find a level to start with, make sure that if it is below college level, in the end you work your way up to college algebra. 

The beauty of this is it is individualized.  You can go at your own pace at the comfort of your own computer.  You know better than anyone else what your algebra skills are.
