Theorem bezoutlemzz 11986

Description: Lemma for Bézout's identity. Like bezoutlemex 11985 but where ' z ' is any integer, not just a nonnegative one. (Contributed by Mario Carneiro and Jim Kingdon, 8-Jan-2022.)

Assertion

Ref	Expression
bezoutlemzz	|- ( ( A e. NN0 /\ B e. NN0 ) -> E. d e. NN0 ( A. z e. ZZ ( z || d -> ( z || A /\ z || B ) ) /\ E. x e. ZZ E. y e. ZZ d = ( ( A x. x ) + ( B x. y ) ) ) )

Distinct variable groups:   A, d, x, y   B, d, x, y   z, A, d   z, B

Proof of Theorem bezoutlemzz

Dummy variable w is distinct from all other variables.
