I have this expression :
1/4 (-Inactive[Cj][j]^2 - 2 Inactive[Cj][j]^3) Inactive[
SixJSymbol][{j, j, j}, {j, j, j}] -
1/2 Inactive[Cj][j] Inactive[triple456][j, j, j, j, j, j]
As you can see, there is a "not simplified" polynomial in front of the SixJSymbol
. I would like Mathematica to replace this part with -(1/4) Inactive[Cj][j]^2 (1 + 2 Inactive[Cj][j])
, i.e. $((-1/4)Cj^2(1+2*Cj))$.
I could do this manually, but I want to know if it is possible to tell Mathematica something like : "Consider that I have a polynomial expression in SixJSymbol
and triple456
, I want that you simplify the factors in front of each of those terms". (If I basically do a Simplify
here, I will no longer have a "factorisation" by SixJsymbol
and triple456
).
Is this possible ? If it is, I would like the simplest way to do it.
