Will name brainliest asap! multiply the binomial and find the (x + y)1 = x + y coefficients:(x + y)2 = x2 + xy + y2 coefficients:(x + y)3 = x3 + x2y + xy2 + y3 coefficients:(x + y)4 = x4 + x3y + x2y2 + xy3 + y4 coefficients:

Important:  to denote exponentiation use " ^ ":

(x + y)1 = ___ x + ___ y    NO
(x + y)^1 = ___ x + ___ y   YES

(x+y)^1 = 1x + 1y

(x+y)^2 = 1x + 2xy + y^2

(x+y)^3 = 1x^3 + 3x^2*y + 3x*y^2 + y^3

and so on.   Look up "Pascal's Triangle" if you want more info on this pattern.



(x + y)4 = ___ x4 + ___ x3y + ___ x2y2 + ___ xy3 + ___ y4    NO

(x + y)^4 = ___ x^4 + ___ x^3y + ___ x^2y^2 + ___ xy^3 + ___ y^4    YES

 (x+y)^4 =  1x^4 + 4x^3*y + 6x^2*y^2 + 4x*y^3 + y^4

The variables should add up to equal 1
