Boa noite a todos...

02. Ache todos os pares tais de n=FAmeros inteiros (x, y) tais que:
x^3 + y^3 =3D (x + y)^2

(x+y)(x^2 - xy + y^2 - y - x) =3D 0

x + y =3D 0  ou  x^2 - xy + y^2 - y - x =3D 0

Seria esse o caminho? ou ser=E1 que tem outro melhor?

n=E3o consegui muit coisa a respeito dessa segunda equa=E7=E3o!!!

Desde j=E1 agrade=E7o a todos!
