    Proof for x^n-y^n=(x-y)(x^n-1+ +y^n-1)

    Proof for x^n-y^n=(x-y)(x^n-1+...+y^n-1) Homework Statement The question asks to prove that for any n\geq1, x^{n}-y^{n}=(x-y)(x^{n-1}+x^{n-2}y+...+y^{n-1}) Homework Equations x^{n}-y^{n}=(x-y)(x^{n-1}+x^{n-2}y+...+y^{n-1}) The Attempt at a Solution So far, I used induction...
