find the LCD for the given rational expressions, and then convert each retional expression into an equivalent rational expression with the LCD as the common denominator.
4/(x-y) and 5x/(2y-2x)
-----------------------
Factor:
4/(x-y) and 5x/[-2(x-y)]
---
LCD: -2(x-y)
---
Rewrite each fraction with LCD as its denominator:
(-2*4)/LCD and (5x)/LCD
----
-8/(-2(x-y)) and 5x/(-2(x-y))
