For more information about quadratic polynomials, see Quadratic polynomial. A quartic equation is a fourth-order polynomial equation of the form. A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable. Monomial – is a polynomial with only one term.

Binomial – is polynomial with two terms.
Trinomial – is a polynomial with four or more terms.
Polynomial – is a polynomial with three terms.
Constant – a polynomial of degree zero.
Linear – a polynomial of degree one
Quadratic – a polynomial of degree two
Cubic – a polynomial of degree three
Quartic – a polynomial of degree four
Quintic – a polynomial of degree five
Degree – is the highest exponents or the highest sum of exponents of the variables in a term

A population is all the organisms that both belong to the same group or species and live in the samegeographical area. In ecology the population of a certain species in a certain area is estimated using the Lincoln Index. The area that is used to define a sexual population is such that inter-breeding is possible between any pair within the area and more probable than cross-breeding with individuals from other areas. Normally breeding is substantially more common within the area than across the border.[1] In sociology, population refers to a collection of human beings. Demography is a social science which entails the statistical study of human populations. This article refers mainly to human population.
