How do I sole
ln(x^(2)  x  2) = 2 + ln(x+1)
This is as far as I have gotten
ln((x^(2)  x  2)/(x+1)) = 2
(x^(2)  x  2)/(x+1) = e^(2)
then I divided because I was too lazy to do algebra
(x+1)(x2) = e^(2)
=
x^(2)x2e^(2) = 0
I'm not allowed to use a calculator
I was thinking I could just sub these numbers into the quadratic formula to come up with solutions would that be the right course of action?

Best ResponseYou've already chosen the best response.3\[x^2x2=(x+1)(x2)\] so you can cancel either first or last

Best ResponseYou've already chosen the best response.3probably easier to do it first, \[\ln((x+1)(x2))=\ln(x+1)+\ln(x+2)=2+\ln(x+2)+\] \[\ln(x1)=2\] \[x2=e^2\] etc

Best ResponseYou've already chosen the best response.3if you can't see the latex i say it in english the x + 1 cancels, you don't get a quadratic

Best ResponseYou've already chosen the best response.3yeah i made a typo too, and put \[x1\] when it should have been \[x2\] but the method is good
