Math Problem Help
Hey guys. So I need some help with a question. It's from a Kumon worksheet btw if you want to know, Level I - Factorization. The example they show is :
(x+y)² + 2(x+y) = (x+y) [(x+y) + 2]
= (x+y) (x+y+2)
And the question I need help is :
x(x+y)² + y²(x+y) =
Thanks!

I don't understand what the question is asking, but I'm assuming this is comprehensive Algebra I.
Lol this type of factoring is so useless! Why they are making you do it, I don't know.
@SmittyKitty yup. thats the one
mfw people think factorising is expanding
x(x+y)² + y²(x+y)
= (x+y)[(x(x+y) + y²]
= (x+y)(x²+xy+y²)
= (x+y)(x²+2xy+y²-xy)
= (x+y)[(x+y)²-xy]
@hareet23 lol, np. grade 8
@SmittyKitty pg. number u mean?
^ = powers
Yes it's factoring, and what does "^" mean?
x(x+y)² + y²(x+y)
= (x+y)[x(x+y)+y²]
= (x+y)[x²+xy+y²]
Something like that? I'm not sure what the goal is.
are you factoring or what?
x(x^2+2y+y^2) + xy^2 + y^3
x^3 +2xy +xy^2 + xy^2 + y^3
x^3 + 2xy + 2xy^2 + y^3
Am I on the right track so far? I'm not sure if what I'm doing is what you're asking lol.
