use expand

I get them combined in 585 with the current master:
pprint(e584)
2⋅b⋅μ -2⋅μ⋅y 2⋅μ⋅x -2⋅μ⋅y -2⋅a⋅μ 2⋅b⋅μ -2⋅a⋅μ 2⋅μ⋅x
- ℯ ⋅ℯ + ℯ ⋅ℯ + ℯ ⋅ℯ - ℯ ⋅ℯ
───────────────────────────────────────────────────────────────────
μ⋅x -μ⋅y -2⋅a⋅μ 2⋅b⋅μ μ⋅x -μ⋅y
- 2⋅ℯ ⋅ℯ + 2⋅ℯ ⋅ℯ ⋅ℯ ⋅ℯ
pprint(e584.powsimp())
-2⋅a⋅μ + 2⋅b⋅μ -2⋅a⋅μ + 2⋅μ⋅x 2⋅b⋅μ - 2⋅μ⋅y 2⋅μ⋅x - 2⋅μ⋅y
ℯ - ℯ - ℯ + ℯ
───────────────────────────────────────────────────────────────────
μ⋅x -μ⋅y -2⋅a⋅μ 2⋅b⋅μ μ⋅x -μ⋅y
- 2⋅ℯ ⋅ℯ + 2⋅ℯ ⋅ℯ ⋅ℯ ⋅ℯ
