Question

what is binomial theorem

Answer 1

The binomial theorem 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 axb yc, where the exponents b and c are non-negative integers with b + c = n, and the coefficient a of each term is a specific positive integer depending on n and b. For example (for n = 4 ),

Answer 2

In elementary algebra, the binomial theorem (or binomial expansion) describes the algebraic expansion of powers of a binomial. ... The coefficient a in the term of a xb ycis known as the binomial coefficient or (the two have the same value). These coefficients for varying n and b can be arranged to form Pascal's triangle.
