minus-square@Cuberoot@lemmynsfw.comlinkfedilink3•2 months ago Your math teacher might not approve of this proof The given examples suffice to prove the general identity. Both sides are obviously degree 4 polynomials, so if they agree at 5 points (include the degenerate case 0^3 = 0^2), then they agree everywhere.
