x+y
x+y multiply.
------
x^2+xy+xy+y^2 now combine like terms.
x^2+2xy+y^2
x+y multiply.
----------
x^3+2x^2y+xy^2+x^2y+2xy^2+y^3 now combine line terms.
x^3+3x^2y+3xy^2+y^3
x+y multiply.
---------------------
x^4+3x^3y+3x^2y^2+xy^3+x^3y+3x^2y^2+3xy^3+y^4 now combine terms.
x^4+4x^3y+6x^2y^2+4xy^3+y^4
x+y multiply.
------------------------------------
x^5+4x^4y+6x^3y^2+4x^2y^3+xy^4+x^4y+4x^3y^2+6x^2y^3+4xy^4+y^5 now combine.
x^5+5x^4y+10x^3y^2+10x^2y^3+5xy^4+y^5 answer.
