Question

a polynomial of n degree has zeroes​

Answer 1

Answer:

it can have only n zeroes because it can't have more than it's degree

Answer 2

Assuming the polynomial is non-constant and has Real coefficients, it can have up to n Real zeros. If n is odd then it will have at least one Real zero. Since any non-Real Complex zeros will occur in Complex conjugate pairs the possible number of Real roots counting multiplicity is an even number less than n.
