I have no idea how to go about this in a general way, but currently break-up fraction isn't very smart.

For example, (2x+3)/(2x+2) simplifies to 2 x / (2 x + 2) + 3 / (2 x + 2), which is arguable more complex. Instead, it might be better if it did: (2x+3)/(2x+2) -> (2x+2 + 1)/(2x+2) -> (2x+2)/(2x+2) + 1/(2x+2) -> 1 + 1/(2x+2).

Thoughts?
