WebAug 26, 2016 · A near "geometric mean" that handles zeros and negative numbers. By definition of a geomean, a geometric mean of a set of numbers containing zero is 0. … WebThe classical geometric mean is defined as the exponentiated mean of log-transformed values. Said another way, it is the nth root of the product of n numeric values. This formula is analogous to geometric distance. The formula does not allow negative values, however, and if any value is zero the result is also zero.

The polynomial p (x)= (x-1) (x-3)² is a 3rd degree polynomial, but it has only 2 distinct zeros. This is because the zero x=3, which is related to the factor (x-3)², repeats twice. This is called multiplicity. It means that x=3 is a zero of multiplicity 2, and x=1 is a zero of multiplicity 1. intel 8086 has transistors
