I am assuming that you probably meant this fraction:
%28y+%2B+5%29%2F+%28y+-+5%29+-+%282y%29%2F+%28y%5E2+-+25%29

First, factor the second denominator in order to find the LCD:
%28y+%2B+5%29%2F+%28y+-+5%29+-+%282y%29%2F+%28%28y+-+5%29%2A%28y%2B5%29%29
The LCD is %28y-5%29%2A%28y%2B5%29

Now, in order to subtract the fractions, you must get the LCD in the first fraction, by multiplying the numerator and denominator of the first fraction by (y+5).


Multiply out the first numerator:


Combine the numerators:
+%28y%5E2+%2B8y+%2B+15%29+%2F+%28%28y-5%29%2A%28y%2B5%29%29+
