Re: Another question about Factor

Dear Nasser,
There is another problem when using HornerForm: the numbers in the express haven't been combined, for example:
k11 = 1/60 (b1^2 + c1^2 + d1^2)
k11 = HornerForm[k11]
The outputs are:
1/60 (b1^2 + c1^2 + d1^2)
b1^2/60 + c1^2/60 + d1^2/60
respectively.
How to do to let the numbers are also been combined?
Thanks,
Tang Laoya
