```I posted a message recently (Integration...Constants) that received
the actual problem:

In:=Integrate[(-2 x+ao)^-2 (-x+bo)^-1, x]

Mathematica gives the following output:

Out=-(1/((ao-2 bo)(ao- 2 x))) - (Log(-bo+x)/(ao^2 - 4 ao bo + 4 bo^2)) +

Log(-ao + 2 x)/(ao^2 - 4 ao bo + 4 bo^2)

This answer is incorrect.  If performed by hand, the answer is shown to
have positive values for ao and bo.  This is confirmed by the fact that
this integration is a classical result of chemistry.  Years of chemical
reaction rate analysis show the values to be positive.  Again, this
calculation was performed using the unix version of 2.2.3.  Any help from
those who have already responded would be most appreciated.
