    the answer is 2x-8 / (x+5)(1-x) i tried the quotient rule but couldnt get the answer can u show how to do it? thanks

    you break the ln into 2 parts. because it is a quotient. so the right side = ln ((1-x) - ln (x+5)^3 . and then take derivative as usual, part to part. try that way.

    don't forget ln(x+5)^3 = 3ln(x+5). I checked and it works.

    use some log laws to simplify the question \[\ln(\frac{1-x}{(x + 5)^3}) = \ln(1 - x) - 3\ln(x + 5)\] once you get the derivatives... to simplify you will need a common denominator of (1 - x)(x + 5) cross multiply for the numerators.
