Subtract and simplify if possible
d%2F%28s%2Bd%29+-+d%2F%28s-d%29
:
The common denominator; (s+d)(s-d), therefore we have
%28d%28s-d%29+-+d%28s%2Bd%29%29%2F%28%28s%2Bd%29%28s-d%29%29
:
Multiply what's inside the brackets
%28ds+-+d%5E2+-+ds+-+d%5E2%29%2F%28%28s%2Bd%29%28s-d%29%29
:
Combining like terms we have
%28-2d%5E2%29%2F%28%28s%2Bd%29%28s-d%29%29
:
FOIL the denominator (the difference of squares)
%28-2d%5E2%29%2F%28s%5E2+-+d%5E2%29
Or
-%282d%5E2%29%2F%28s%5E2+-+d%5E2%29
