Question

x^2-y^2+x-y

Answer 1

`!`

`x^2-y^2+x-y`

`= (x-y)(x+y)+(x-y)`

`= (x-y)(x+y+1)`

Answer 2

=(x-y)(x+y)+(x-y)

=(x-y)(x+y+1)

Answer 3

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

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

\(=\left(x-y\right)\left(x+y\right)+\left(x-y\right)\)

\(=\left(x-y\right)\left(x+y+1\right)\)
