2x/x^2-9 divided by 4x^2/x-3. I know the first step is to factor (x^2-9), which is (x+3)(x-3), and do the reciprocal, which will now be 2x/(x+3)(x-3) * x-3/4x^2, what else do i do next? Please explain:) Thanks.

here are some theoretical questions about time travel?

well i know that the future is undetermind so travel to the future would be impossible, but if a person could travel backward in time, how would the expansion of the universe affect time travel, would the person traveling back in time become more dence on a molecular level the farther back he goes, because doesn't the expansion of the universe cause the mass of the universe to expand with it, would time travel to the past be like being in a black hole.
