In elementary algebra, the binomial theorem (or binomial expansion) describes the algebraic expansion of powers of a binomial.

What happens when we multiply a binomial by itself ... many times? a+b is a binomial (the two terms are a and b) Let us multiply a+b by itself using Polynomial Multiplication : (a+b) (a+b) = …

The binomial theorem formula is (a+b) n = ∑ nr=0n C r a n-r b r, where n is a positive integer and a, b are real numbers, and 0 < r ≤ n. This formula helps to expand the binomial expressions …

Nov 30, 2025 · The theorem states that for any given positive integer n, the expansion of the binomial expression (a + b) n can be expressed as the sum of n + 1 terms, where each term is …

The binomial theorem is used to expand polynomials of the form (x + y) n into a sum of terms of the form ax b y c, where a is a positive integer coefficient and b and c are non-negative …

What is the Binomial Theorem? The Binomial Theorem is a handy formula in algebra that helps us expand expressions like (x + y) n without having to multiply everything out by hand. It takes a …

A polynomial with two terms is called a binomial. We have already learned to multiply binomials and to raise binomials to powers, but raising a binomial to a high power can be tedious and …
