For understanding: Binomial Theorem for Rational n
Thank you all for your invaluable help.
I was confused when expanding the above equation as the textbook I am referring to stated different formulae where n is a non-positive integer and when x>1 or x<1.
Can the expansion formula that is used when n is a positive integer be still used when n is a negative integer or when n is not an integer at all?
