I feel like I am going crazy. I have gone over and over this and just cannot figure out where I went wrong.
(And before you mention it, yes, I do know now that when I factored the 60, I could have used 12 and 5 as factors, and this would have given me the right answer (which for the record is (x-4)(-3x+5). But I really want to know why, what I did originally, is not correct, so I can learn from my mistake. Thank you in advance!
