Algebraic expressions which have two terms are called
Binomial expressions
(a + b)n =
an + (n1)an-1b + (n2)an-2b2 + …
(1 + x)n =
1 + nx + (n(n-1) / 2!)x2 + (n(n-1)(n-2) / 3!)x3 + … |x| < 1
Find the range of values for which the expansion of 1 / (1 - 2x)3 is valid
Rewrite as (1 - 2x)-3
and find that the expansion is valid for:
|2x| < 1 → |x| < 1/2.
