The answer depends upon which division is done first. For example:
(a/b)/c = a/(bc), but
a/(b/c) = ca/b
They are NOT the same.
You need to clarify the sequence of operations
If you write 1/a + 1/c as (a+c)/ac, and a^2 - c^2 = (a+c)(a-c)
you can get some cancellations and simplify the expression.
I am not sure how else to put this one on this forum to clarify the sequence, so thank you for your help
