SUMMARY
A non-zero polynomial with coefficients in a field F and of degree n has at most n distinct roots in F. This conclusion is established through mathematical induction on the degree of the polynomial. For degree one polynomials, the proof is straightforward as they can have only one root. The discussion emphasizes the importance of induction as a method for proving this property for higher degree polynomials.
