Question

please answer my quetion [x+y]^2-[x^3+y^3]

Answer 1

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
