y'={-x}/{1+x} MATH IS EXTREMELY RUSTY!! But since you have 5 tries, try that lol.
y = ln[(e^−x) + (xe^−x)] <--- find y prime
Yurp that's it. Will +rep if the answer is correct (I can check it since the HW is online, it will tell me whether or not I get it right, I have 5 tries).
Appreciate it ^.^

Mistry beat me to it, but if you need any explanation/more help I am happy to ^_^!
J_L_K_64 rules you.
damn glad i never took calculus xD and do you use blackboard? jw cause on my online assignments i get 5 tries too xD
You can also try inputting problems like this into (you need an account to see links). Your problem, for instance, could be put in as d/dx ln[(e^−x) + (x*e^−x)] (same as finding y'). It'll show you step-by-step solutions.

What's my definition of success?
Creating something no one else can
Being brave enough to dream big
Grindin' when you're told to just quit
Giving more when you got nothin' left
