WebThe Binomial theorem tells us how to expand expressions of the form (a+b)ⁿ, for example, (x+y)⁷. The larger the power is, the harder it is to expand expressions like this directly. … 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 replaced by an infinite series. In order to do this, one needs to give meaning to binomial coefficients with an arbitrary upper index, which cannot be done using the usual formula with factorials. However, for an arbitrary number r, one can define sharon thorne twitter

The degree (or sum of the exponents) for each term is n. The powers on x begin with n and decrease to 0. The powers on y begin with 0 and increase to n. The coefficients are symmetric. To determine the expansion on (x + y)5, we see n = 5, thus, there will be 5 + 1 = 6 terms.
