x (x+y)

Answer 1

(2xy+x^2+y^2)(x+y) Right?

Answer 2

yes..srry 4 the mistake

Answer 3

its ok lol, you distribute do u know how?

Answer 4

2xy times x is 2x^2y understand? then u keep doing so

Answer 5

ya, but itz 2 many varibles instead of numbers..so I keep on messin up+confused

Answer 6

it would be ,
x^3 + y^3 + 3x^2y + 3xy^2
= (x+y)^3

Answer 7

@sp11 do it slowly ill walk u through it if u want?

Answer 8

123
x 12
