Okay, say I wanted to factor a 0 out of 10. So then I could just say that 10 x 0 = 0? That 0 and 10 would be the two factors? Then I could just multiply them back together to get 10? So if I had (10 + 10 ) = 10 I could just factor out a zero out of both sides? Then I would have 0 ( 20 ) = 10 ( 0 ) Then I would get 0 = 0 Wow Pete, I think you helped me solve this problem! Finally figured it out!
