Apply the Binomial Theorem. 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 time-consuming. In this section, we will discuss a shortcut that will ...
So let's use the Binomial Theorem: First, we can drop 1n-k as it is always equal to 1: And, quite magically, most of what is left goes to 1 as n goes to infinity: Which just leaves: With just those first few terms we get e≈ 2.7083... Try calculating more terms for a ...
Binomial Theorem For Negative Or Fractional Indices : If n∈Q, then(1+x)n=1+nx+n(n-1)/2!+n(n-1)(n-2)/3!+……….Provided | x | < 1. When the index n is a positive integer the number of terms in the expansion of
THE BINOMIAL THEOREM shows how to calculate a power of a binomial—(a + b)n—without actually multiplying.For example, if we actually multiplied out the 4th power of (a + b) --(a + b)4 = (a + b)(a + b)(a + b)(a + b)-- then on collecting like terms we would find:...

a mathematical theorem that gives the expansion of any binomial raised to a positive integral power,n. It containsn+ 1 terms: (x+a)n=xn+nxn--1a+ [n(n--1)/2]xn--2a2+…+ (nk)xn--kak+ … +an, where (nk) =n!/(n--k)!k!, the number of combinations ofkitems selected from...
We know that any algebraic expression with two unlike terms is considered binomial. In the stated expression x2 + 2, we have two non-zero terms joined together by an addition sign in between. What is Binomial Theorem? The binomial theorem is an equation or a formula to find any power of...
Definition: Binomial Theorem Although the Binomial Theorem is stated for a binomial which is a sum of terms, it can also be used to expand a difference of terms. Simply rewrite (x + y) n as (x + (– y)) n and apply the theorem to this sum. Example: Use the Binomial Theorem to...
Binomials are expressions that contain two terms such as (x + y) and (2 – x). The Binomial Theorem states that Note that: The powers of a decreases from n to 0. The powers of b increases from 0 to n. The powers of a and b always add up to n. Binomial Coefficient In the ex...
Among his many other talents, Major General Stanley in Gilbert and Sullivan's operetta the Pirates of Penzance impresses the pirates with his knowledge of the binomial theorem in "The Major General's Song" as follows: "I am the very model of a modern Major-General, I've information vegetabl...
