二项式定理公式的全英文表达是什么?

二项式定理:Binominal theorem
binominal theorem gives the expansion of powers of sums:
(x+y)^n=sigma(k=0,n) C(n,k)x^(n-k)y^k
whenever n is any non-negative interger,
the number c(n,k)=n!/(k!(n-k)!)
is the binomial coefficient(using the choose function),and n!denotes the factorial of n.
