Find the coordinates of the turning point and determine wether it is minimum or maximum.

y=xlnx-2x

The answer in the book says the co-ordinates are (e,-e), the closest I have come is (1/lnx,-1/lnx) which works if 1/lnx=e, but I don't think that it does. This question is in relation to derivatives.
