  • ln(x/x-9) means ln%28x%2Fx-9%29 but I wonder if you intended ln%28x%2F%28x-9%29%29 which would be posted as: ln(x/(x-9)) or ln((x)/(x-9))
  • ln(x+9/x) means ln%28x%2B9%2Fx%29 but I wonder if you intended ln%28%28x%2B9%29%2Fx%29 which would be posted as: ln((x+9)/x) or ln((x+9)/(x))
Please re-post your and put parentheses around numerators and denominators so we tutors don't have to guess what the problem is.
