How does (x+y)^4 factor? What is the factoring pattern?

Question

(x+y)^4

How does this expand/factor? I know there is some sort of pattern, but I forgot it.

If you can factor it, that would be great, or if you just know the factoring pattern... that would be great too! Thanks for any and all help!

Answer 1

It is already factored. You can expand it using the Binomial Theorem. The expansion is
x^4 + 4x^3y + 6x^2y^2 + 4xy^3 + y^4.

Answer 2

hi, i'm french
u can't factor because it's a product
U must espand it:(x+y)^4=(x+y)^2*(x+y)^2=(x^2+2*x*y+y^2)*(x^2+2*x*y+y^2)=x^4+4*x^3*y+6*x^2*y^2+4*x*y^3+y^4.
