“A makes B good, and so does C”

Question

This sentence is the short form of "A makes B good, and C makes B good too."

Then, what is the short form of "A makes B good, and A makes C good too?"

Answer 1

Possibly:

A makes B good, as well as C.

Though this may be ambiguous (though it will probably be obvious from context).

Maybe this would be better:

A makes B good, and makes C good as well.

Perhaps just say

A makes B and C good.

Answer 2

A makes both B and C good.

A makes either B or C good.

The latter could be used if A does not do so concurrently.

Answer 3

Either A or C makes B good

or

B is good due to either A or C

or

Both A and C make B good

However, the last form, implies that A and C are required simultaneously to make C good.

EDIT, post comment.

A makes B good, as does C
