Original question and givens

Use boundary exponent=-17. Give (exponent, finite_polynomial_claim, boundary).

  • G001 — Use boundary exponent=-17. Give (exponent, finite_polynomial_claim, boundary).

Definition and scope

The finite binomial expansion needs a nonnegative integer exponent. Only that finite-polynomial claim is withheld; other series are not disproved.

Step-by-step derivation

S001 · implies

Before

exponent=-17

After

finite polynomial formula requires a nonnegative integer n

Conditions: none

The finite-product theorem requires a nonnegative integer exponent.

Step identifiers and dependencies

Rule: natural_exponent · Uses: G001

S002 · implies

Before

exponent=-17

After

not a permitted finite-product exponent

Conditions: none

A negative or noninteger exponent is outside this finite expansion's declared domain.

Step identifiers and dependencies

Rule: exponent_rejection · Uses: G001, S001

S003 · implies

Before

finite product with n factors

After

cannot enumerate a negative/noninteger number of factors

Conditions: none

Consequently the finite coefficient list k=0 through n cannot be applied directly.

Step identifiers and dependencies

Rule: finite_factor_count · Uses: G001, S002

S004 · implies

Before

this finite theorem is inapplicable

After

no claim about a different generalized binomial series

Conditions: none

This does not disprove generalized series under other convergence hypotheses, and it does not drop commutativity.

Step identifiers and dependencies

Rule: scope_not_global_disproof · Uses: G001, S003

Reverse checks

  • S004 · premise_and_result_audit — Count coefficients in the integers first; do not invert possibly nonunit factorials in a general coefficient ring.
  • S003 · premise_and_result_audit — Count coefficients in the integers first; do not invert possibly nonunit factorials in a general coefficient ring.
  • S002 · premise_and_result_audit — Count coefficients in the integers first; do not invert possibly nonunit factorials in a general coefficient ring.
  • S001 · premise_and_result_audit — Count coefficients in the integers first; do not invert possibly nonunit factorials in a general coefficient ring.

Result

(-17, No, finite_binomial_polynomial_requires_natural_zero_exponent_and_commutative_multiplication)

The full substitutions and premise audits recover the original answer, retaining its field order and verdict meanings.
