In elementary algebra, the binomial theorem (or binomial expansion) describes the algebraic expansion of powers of a binomial. According to the theorem, it is possible to expand the polynomial ( x + y ) n into a sum involving terms of the form ax b y c , where the exponents b and c are nonnegative integers with b + c = n , and the coefficient a ...
The binomial theorem states the principle for expanding the algebraic expression (x + y) n and expresses it as a sum of the terms involving individual exponents of variables x and y. Each term in a binomial expansion is associated with a numeric value which is called coefficient.
Learn how to multiply a binomial by itself many times using the Binomial Theorem. See the pattern, the formula, the coefficients, and examples of binomial expansions.
10 cze 2024 · The binomial theorem is a formula for expanding binomial expressions of the form (x + y) n, where ‘x’ and ‘y’ are real numbers and n is a positive integer. The simplest binomial expression x + y with two unlike terms, ‘x’ and ‘y’, has its exponent 0, which gives a value of 1. (x + y) 0 = 1.

Solution. We have a = p and b = 3q, and n = 5 and k = 4. Thus, the binomial coefficient of the 4 th term is (5 3), the b -term is (3q)3, and the a -term is p2. The 4 th term is therefore given by. (5 3) ⋅ p2 ⋅ (3q)3 = 10 ⋅ p2 ⋅ 33q3 = 270p2q3. In this case, a = x3y and b = − 2x2, and furthermore, n = 10 and k = 8.
The binomial theorem (or binomial expansion) is a result of expanding the powers of binomials or sums of two terms. The coefficients of the terms in the expansion are the binomial coefficients \( \binom{n}{k} \).
