Subtract and simplify if possible:
6/5r^2 - 7/5r-5
----------------
[6/5r^2] - [7/(5(r-1)]
----
least common denominator: 5r^2(r-1)
-----------------
Rewrite each fraction with the lcd as its denominator:
[6(r-1)/lcd] - [7r^2/lcd]
----
Combine the numerators over the lcd:
---
[-7r^2+6r-6]/[5r^2(r-1)]
----
