Animal biosecurity is the product of all actions undertaken by an entity to prevent introduction of disease agents into a specific area. Animal biosecurity differs from biosecurity which are measures taken to reduce the risk of infectious agent theft and dispersal by means of bioterrorism. Animal biosecurity is a comprehensive approach, encompassing different means of prevention and containment. A critical element in animal biosecurity, biocontainment, is the control of disease agents already present in a particular area, and works to prevent novel transmissions.
Polynomials are often the product of smaller polynomial factors. Binomial factors are polynomial factors that have exactly two terms. Binomial factors are interesting because binomials are easy to solve, and the roots of the binomial factors are the same as the roots of the polynomial. Factoring a polynomial is the first step to finding its roots.
The only time you will get a binomial back as an answer is if both of your binomials share like terms like in this example. Our first binomial is 5x+3y and our second binomial is 4x+7y. The first term of both binomials have the same variable to the same exponent, x. The second term of both binomials also shares a variable to the same exponent, y. We can go ahead and combine the first terms (5x and 4x) together because they are like terms. We can do the same for the second terms (3y and 7y).
