Several variables, consider polynomail as polynomial only of $X$, group coefficients
Suppose I have variables
x and I somehow using symbolic calculation get polynomial like this:
$$9d^2e^2x^2 - 36d^2ex^3 + 18de^2x^2$$
I want sage to group coefficients at
x and consider my polynomial as polynomial only of
x, I want other variables to be no more than just parameters. In short I want to see something like this:
$$9de^2(d + 2)x^2 - 36d^2ex^3$$
Is it possible to exploit such an approach in Sage?
P.S. I shortened my example. In real life example it is not so easy to see such a grouping by hands.
