Polynomials in one variable are algebraic expressions that consist of terms in the form where n is a non-negative (i.e. positive or zero) integer and a is a real number and is called the coefficient of the term. The degree of a polynomial in one variable is the largest exponent in the polynomial. Note that we will often drop the âin one variableâ part and just say polynomial. Here are examples of polynomials and their degrees. So, a polynomial doesnât have to contain all powers of x as we see in the first example.
The multiplicity of a zero of a polynomial function is how many times a particular number is a zero for a given polynomial. For example, in the polynomial function , the zeros are 0 with a multiplicity of 1, -4 with a multiplicity of 2, and 2 with a multiplicity of 3. Although this polynomial has only three zeros, we say that it has six zeros (or degree of 6) counting the multiplicities.
