Question

x ^ 3 - x + 2y - 8y ^ 3

Answer 1

\(x^3-x+2y-8y^3\)

\(=\left(x^3-8y^3\right)-\left(x-2y\right)\)

\(=\left(x-2y\right)\left(x^2+2xy+4y^2\right)-\left(x-2y\right)\)

\(=\left(x-2y\right)\left(x^2+2xy+4y^2-1\right)\)

Answer 2

`x^3 - x + 2y - 8y^3`

`= x^3 - 8y^3 - (x - 2y)`

`= x^3 - (2y)^3 - (x-2y)`

`= (x-2y)(x^2 + 2xy + 4y^2) - (x-2y)`

`= (x-2y)(x^2 + 2xy + 4y^2 - 1)`
