Write a rational expression, in its simplest form, that represents the sum of the reciprocals of the squares of the consecutive even integers n-2, n, and n+2. That is the expression should be in terms of the integer variable n.
:
Assume this problem means:
+ +
:
Place the expression over a single denominator:

:
FOIL all those squares:

:
Multiply (n^2-4n+4)(n^2+4n+4) the vertical way, you should get:
; then we have:

:
Group like terms in the numerator and mult in the denominator:
=
:
is what I get here, hope this helps you.
