Binomials are expressions that contain two terms such as (x + y) and (2 – x).
The Binomial Theorem states that
1) The powers of a decreases from n to 0.
2) The powers of b increases from 0 to n.
3) The powers of a and b always add up to n.
In the expansion of (a + b)n, the (r + 1)th term is
a) (a + b)5
b) (2 + 3x)3
