Rearrange a product whose right operand is a product including a constant such that constants are grouped on the left:
![\[ \alpha (\beta u) \rightarrow (\alpha\beta) u \]](form_131.png)
![\[ u (\alpha v) \rightarrow \alpha (u v) \]](form_132.png)

Test whether the transform is applicable in this case, and if it is, apply it.
The return value is true is the transformation was applied, otherwise false. Returns by non-const reference the transformed expression.
