    There is nothing that can be done with x^2+y^2, it is a prime expression, irreducible.

    We can factor the difference x^2-y^2=(x+y)(x-y) but not the sum.

    Hello, blackjack21!

    Even if you had x^2y^2, there's nothing to be done.

    Well, you could write it as: . (xy)^2 .. . . but that's all.

    If you understand that -1+4=3 then there is no additional rules to apply.
