    Answer:

    hope this helps u

    Step-by-step explanation:

    [x+y]^2-[x^3+y^3]

    expand using the identities

    [x+y]²=x²+2xy+y²

    [x³+y³- [x+y][x²-xy+y²]

    x²+2xy+y²-[x+y][x²-xy-y²] here we have minus that is common for  [x+y] [x²-xy-y²]  multiple it to [x+y] [x²-xy-y²]

    x²+2xy+y²-x-y-x²+xy-y² subtracting  

    2xy-x-y+xy

    3xy-x-y
