Question

x^3+y^3+x+y

Answer 1

\(x^3+y^3+x+y\)

\(=\left(x^3+y^3\right)+\left(x+y\right)\)

\(=\left(x+y\right)\left(x^2-xy+y^2\right)+\left(x+y\right)\)

\(=\left(x+y\right)\left(x^2-xy+y^2+1\right)\)

Answer 2

$#flo$

`x^3 + y^3 + x + y`

`=(x + y)(x^2 - xy + y^2) + (x + y)`

`= (x + y)(x^2 - xy + y^2 + 1)`
