Simplify. 9. (x^3 + y^3) / (x + y)

So it becomes x^2 + y^2

OpenStudy (firejay5):

are you making sure to do long division that is dividing by polynomials

OpenStudy (anonymous):

Does it say to use long division?

OpenStudy (anonymous):

or else it's

OpenStudy (anonymous):

(x+y) (x^2+y^2)

OpenStudy (anonymous):

that would be equal to your first equation.

OpenStudy (anonymous):

But it says simplify.... so I guess it's just x^2 + y^2

OpenStudy (firejay5):

we use long division though

OpenStudy (anonymous):

Well your answer is x^3 + y^3/(x+y) = (x+y) (x^2 + y^2) Although it says simplify.

OpenStudy (firejay5):

The answer is x^2 - xy _ y^2

OpenStudy (anonymous):

What's between the xy and y^2?

OpenStudy (firejay5):

I meant - y^2

OpenStudy (anonymous):

I have no idea how you got that... To me, that makes no sense.

OpenStudy (firejay5):

Lol it's dividing polynomials

OpenStudy (firejay5):

yes @Australopithecus

OpenStudy (anonymous):

I've done long division.... I've done dividing polynomials....I still don't see how...

OpenStudy (firejay5):

Like how's it done
