Default Error in formula displayed for linear and 2nd order curve fits inExcel 2003

I have created trendlines for some pretty simple data using both 2nd
order polynomial and linear fits. In both cases, the displayed
formulas have their 1st and 2nd order coefficients wrong by a factor
of 10!! (I have read lots of posts about increasing precision but this
is not what I am up against). Has anyone seen this?
