Homework Statement
if a and b are odd integer, then 8 l (a2-b2)
Homework Equations
n/a
The Attempt at a Solution
if a=b, clearly, 8 l (a2-b2)
if not,
now, I'm not sure how to continue
should i varies b, and make a fixed, then varies a, and make b fixed,
is that really the way to show, for all odd integer a and b?
