You can put this solution on YOUR website! you can factor something without finding zeros. is an expression that factors to (x+2)(x-2), and you can factor out a 2 from the expression 2x+4 and you will be left with 2(x+2) you will not get x= something, but you are still factoring.
If you want to work some problems on an online whiteboard, then send me an email and I will be happy to help you. We can work out this problem and others until you feel comfortable with doing these on your own. We can also talk over the phone or through skype.
All of this is provided on a volunteer basis and is first come first serve (although I haven't had a huge acceptance of this offer so there is a good chance I will be able to help you right away).
