Theorem rabdiophlem2 39743

Description: Lemma for arithmetic diophantine sets. Reuse a polynomial expression under a new quantifier. (Contributed by Stefan O'Rear, 10-Oct-2014.)

Hypothesis

Ref	Expression
rabdiophlem2.1	⊢ 𝑀 = (𝑁 + 1)

Assertion

Ref	Expression
rabdiophlem2	⊢ ((𝑁 ∈ ℕ0 ∧ (𝑢 ∈ (ℤ ↑m (1...𝑁)) ↦ 𝐴) ∈ (mzPoly‘(1...𝑁))) → (𝑡 ∈ (ℤ ↑m (1...𝑀)) ↦ ⦋(𝑡 ↾ (1...𝑁)) / 𝑢⦌𝐴) ∈ (mzPoly‘(1...𝑀)))

Distinct variable groups:   𝑢,𝑁,𝑡   𝑢,𝑀,𝑡   𝑡,𝐴

Allowed substitution hint:   𝐴(𝑢)

Proof of Theorem rabdiophlem2

Dummy variable 𝑎 is distinct from all other variables.
