Math  Write expression as single logarithm
posted by CheezyReezy on .
Write the expression below as a single logarithm. Please show all of your work.
ln((x^2 – 1)/(x^2 – 6x + 8)) – ln((x+1)/(x+2))

ln((x^2 – 1)/(x^2 – 6x + 8)) – ln((x+1)/(x+2))
when you subtract the logs, you divide the arguments
ln (x+1)(x1) / [(x+1)(x1)((x4)(x2)]
ln 1/[(x4)(x2)]
ln [ (x4)(x2) ]^1
ln [ (x4)(x2)]
