What is binomial expansion?

 

[Tide]

A binomial expansion is the expansion of a repeated product or power of a binomial expression such as $(a + b)^n$. "Binomial" simply means "two terms."

Binomial expansion is a mathematical process used to expand a binomial expression, which is an algebraic expression with two terms. It is a method of raising a binomial expression to a power, where the exponent is a positive integer. The expansion involves multiplying the binomial expression by itself a certain number of times, depending on the exponent, and then simplifying the resulting expression. The binomial expansion formula is expressed as (a + b)^n = a^n + na^(n-1)b + (n(n-1)/2!)a^(n-2)b^2 + ... + b^n, where a and b are the two terms in the binomial expression, and n is the exponent. This process is useful in simplifying and solving complex algebraic equations, and it is a fundamental concept in algebra and calculus.
