Needing help with these problems lost, subtract. simplify if possible 3/x-9 - 3/ 9-x, divide and simpliify 6/t divide 18/t, add. simplify is possible 5/z-8 + 12/(z-18)^2
I am not sure if I have the problems right. For what I think is the first question:
3/(x-9) - 3/(9-x)
However, (9-x) = -1(x-9)
Therefore 3/(x-9) - 3/(9-x) = 3/(x-9) + 3/(x-9) =
I hope this helps. If not, please repost, clarifying your questions. Thanks for asking.
