Question

What is binomial theorem

Answer 1

 binomial theorem (or binomial expansion) describes the algebraic expansion of powers of a binomial.
 The binomial theorem is pretty interesting. 

The statement is as follows: 

Given the definition of (nCk), the following is true: 

(x+y)^n = 

(nC0) x^n + (nC1) x^(n-1)y + (nC2) x^(n-2) y^2 + ... (nCn-1)x y^(n-1) + (nCn) y^n 

You can write this using Σ notation: 

(x+y)^n = Σ (nCk) x^(n-k) y^k 

where 0≤k≤n. 

Answer 2

binomial theorem is a formula for funding any power of a binomial without multiplying at length
