2 3
----- - -------
5w+10 2w-4
-----------
Factor the denominators, as follows:
[2/(5(w+2)] - [3/(2(w-2)]
The LCD is 10(w+2)(w-2)
Write each fraction over the LCD, as follows:
[2(2(w-2)]/LCD - [3(5(w+2)]
Combine the numerators over the LCD, as follows:
[2(2w-4)-3(5w+10)]/LCD
[4w-8-15w-30]/LCD
[-11w-38]/[10(w+2)(w-2)]
