    Binomial theorem - Wikipedia

    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) into a sum involving terms of the form ax y , where the exponents b and c are nonnegative integers with b + c = n, … See more

    Special cases of the binomial theorem were known since at least the 4th century BC when Greek mathematician Euclid mentioned the special case of the binomial theorem for exponent See more

    Here are the first few cases of the binomial theorem:
    • the exponents of x in the terms are n, n − 1, ..., 2, 1, 0 (the last term implicitly contains x = 1);
    • the exponents of y in the terms are 0, 1, 2, ..., n − 1, n (the … See more

  11. Binomial Theorem | Brilliant Math & Science Wiki

    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} (kn).
