factor this expression here you to realize that this is actually a difference of squares that's the power for is actually exclude also very by the power for its actually y squared. Also so using difference of squares which tells us Oh yeah, minus east that gets factored into eight plus e turns a minus. So that means our expression here is excluded. Waas twice there and x squared minus y squared. So the first term, um, his partner to be kept factor that. But the second term, as we can see, is again a difference of squares to that Music can fracture that second term again so that used as becomes expect voice three because we can't factor that and an explorer minus y squared becomes exp less Why trains x minus way
