Expanding a binomial with a high exponent such as \({(x+2y)}^{16}\) can be a lengthy process. Sometimes we are interested only in a certain term of a binomial expansion. We do not need to fully expand a binomial to find a single specific term.

The Binomial Theorem: Examples Purplemath
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 2. There is evidence that the binomial … 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 first term implicitly contains y … See more The binomial theorem is valid more generally for two elements x and y in a ring, or even a semiring, provided that xy = yx. For example, it … See more • The binomial theorem is mentioned in the Major-General's Song in the comic opera The Pirates of Penzance. • Professor Moriarty is described by Sherlock Holmes as having written a treatise on the binomial theorem. See more The coefficients that appear in the binomial expansion are called binomial coefficients. These are usually written Formulas See more Newton's generalized binomial theorem Around 1665, Isaac Newton generalized the binomial theorem to allow real exponents other than nonnegative integers. (The same generalization also applies to complex exponents.) In this generalization, the finite sum is … See more • Mathematics portal • Binomial approximation • Binomial distribution • Binomial inverse theorem See more WebApr 10, 2024 · Very Long Questions [5 Marks Questions]. Ques. By applying the binomial theorem, represent that 6 n – 5n always leaves behind remainder 1 after it is divided by 25. Ans. Consider that for any two given numbers, assume x and y, the numbers q and r can be determined such that x = yq + r.After that, it can be said that b divides x with q as the … WebApr 8, 2024 · Middle Term of Binomial Expansion. The Middle Term of a Binomial Expansion is the term that comes in the middle of the expansion of the binomial, given by the Binomial Theorem. If the power of expansion of the sum or difference of two terms is an even number, then there is only one middle term. Otherwise, there are two middle … to interrupt a process by name we use
