Question

How do you use the Binomial Theorem to expand ( 1 - x ) − 1 ?

Answer 1

Step-by-step explanation:

Now,

This binomial expansion formula gives the expansion of (1 + x)n where 'n' is a rational number. This expansion has an infinite number of terms. (1 + x)n = 1 + n x + [n(n - 1)/2!] x2 + [n(n - 1)(n - 2)/3!]
