I have two expression like,
exp1:=A1*x*(k-p*x)+A2*x+A3*p+A4
exp2:=A5*x*(k-p*x)
where A1, A2, A3, A4 and A5 are some lengthy expressions.
I need to find the division of these two, namely exp3
exp3:=exp1/exp2
in the form
exp3:=(A1/A5)+the rest
In other words, I need to extract the part which could be normalized by x*(k-p*x).
