Polynomial Functions of Higher Degrees
If a is a zero of a polynomial and the exponent on the term that produced the root is k then we say that a has multiplicity k.
Zeroes with a multiplicity of 1 are called simple zeroes.
A factor (x - a)k , k > a yields a repeated x = a zero of multiplicity k.
Real Zeros of a Polynomial Functions If f is a polynomial function and a is a real number, the following statements are equivalent.
x = a is a zero of the function f .
x = a is a solution of the polynomial equation f (x) = 0 (x - a) is a factor of the polynomial f (x)
