# Binomial system

See Article History Nomenclature, in biological classificationsystem of naming organisms. In our last method, we studied the FOIL method for multiplying binomials. We can still apply the FOIL method when we square binomials, but we will also discover a special rule that can be applied to make this process easier.

Let's take a look at Example 1. Investigating the Square of a Binomial Let's take a look at a special rule that will allow us to find the product without using the FOIL method.

The square of a binomial is the sum of: I know this sounds confusing, so take a look. If you can remember this formula, it you will be able to evaluate polynomial squares without having to use the FOIL method.

It will take practice. Now let's take a look at Example 1 and find the product using our special rule. Using the Special Rule Now let's take a look at another example. This time we are going to square a binomial, but this binomial will contain a subtraction sign.

Did you notice that the middle term is negative this time? Let's quickly recap, and look at the definition for Squaring a Binomial.

You might want to record this in your Algebra notes. Squaring a Binomial Are you ready to practice? Practice Problems Problem 1: Now you are ready to study a new special rule which is called the "Difference of Two Squares.The system used in science to name an organism, consisting of two terms, the first being the genus and the second the species.

Passer domesticus, the scientific name of the common house sparrow, is an example of binomial nomenclature. Counts and Proportions as Dependent Variables If your dependent variable represents a count (e.g., the number of injuries in different sports) or a proportion (e.g., the percent of Type I muscle fibers in a muscle biopsy from different athletes), analysis can be a challenge.

Once again, the problem with the usual analyses is the possibility of violation of one or more of the assumptions we.

a system of nomenclature in which each species of animal or plant receives a name of two terms of which the first identifies the genus to which it belongs and the second the species itself. This two word Latin name is known today as binomial nomenclature (binomial – means two names, nomenclature – is the system used for naming things).

Importance of Binomial Nomenclature Before Linnaeus came along and simplified things, plants usually had many long descriptive Latin names, making learning and memorizing them very .

How to Write a Scientific Name. The system of nomenclature used today is based on the binomial system of nomenclature, developed by Linnaeus in the late 's.

The binomial system of nomenclature is structured so that the scientific name of a plant consists of two names: (1) the genus or generic name, and (2) the specific epithet or species name.
