Find the derivative

Question

y = 3x+2/x+1

Answer 1

See what happens if you don't use brackets ???

Jana, myself and Steve gave correct answers depending on which interpretation we give to your question.

Please use brackets.

Answer 2

Hmmm :-)

Actually, I was just looking at that again, and Jana's answer is incorrect. She said

3 + 2ln|x|

That is the derivative of 3x + the antiderivative of 2/x!

Still, her work indicated a possible interpretation of the syntax...
