But when you "factor out" the -1, it has to go somewhere, you can't just drop it , so ...
(4)/(x-3) + (2)/(-1)(-3+x)
= 4/(x-3) - 2/(-3+x)
= 2/(x-3)
remember what I showed you yesterday?
2/-1 = -2/1 = -(2/1)
(4)/(x-3)+(2)/(3-x)
(4)/(x-3) + (2)/(-1)(-3+x)
i factor out a negative 1 from 3-x.
4/(x-3)+ 2/(x-3)
6/x-3
it suppose to be 2/x-3 how i get that?
