The Binomial Theorem

binomial theorem used to find individual terms of an expression

(x+y)^n=nsigmar=0n!/(r!(n-r)!)x^(n-r)y^r when finding a specific term subtract it by 1 and replace the r with that number

binomial theorem

(x+y)^n=x^n+nx^(n-1)y+(n(n-1))/2x^(n-2)y^2+(n(n-1)(n-2))/6x^(n-3)y^3+...+y^n
