wat is a polynomial?

Question

i need to noe

Answer 1

In mathematics, a polynomial is an expression in which a finite number of constants and variables are combined using only addition, subtraction, multiplication, and positive whole number exponents (raising to a power).

A polynomial function is a function defined by evaluating a polynomial. For example, the function f defined by f(x) = x3−x is a polynomial function. Polynomial functions are an important class of smooth functions; smooth meaning that they are infinitely differentiable, i.e., they have derivatives of all finite orders.

Because of their simple structure, polynomials are easy to evaluate, and are used extensively in numerical analysis for polynomial interpolation or to numerically integrate more complex functions.

Answer 2

In mathematics, a polynomial is an expression in which constants and variables are combined using only addition, subtraction, multiplication, and positive whole number exponents. Thus,

2 x^2 y z^3 - 3 y^2 + 5 y z - 2 \,

is a polynomial, but

{1 \over x^2 + 1} \,

is not a polynomial.

Answer 3

An n-th degree polynomial of a variable x is an expression of the form

a[n]*x^n+a_[n-1]*x^(n-1)+...+a[2]*x^2+a[1]*x+a[0].

Here, a[n], a[n-1], ..., a[2], a[1] and a[0] are arbitrary real numbers, and x is a variable (an unknown).

For example, x^2-2*x+3 is a second degree polynomial, 10*x-7 is a first-degree polynomial and a polynomial of degree 0 is just a number.

In other words, n-th degree polynomials are expressions which may only contain powers of an unknown up to the power n, and these powers can be multiplied by arbitrary numbers and then added.

One can also talk about polynomials of several variables. If you're interested in further facts about polynomials, I recommend you to visit http://en.wikipedia.org/wiki/Polynomial.

Answer 4

a math equation

2x -monomial
2x-3 -binomial
1x+2x-3 -trinomial

any equation that has a variable and/or a term is a polynomial

more specific an equation that has one term is a monomial, 2 terms is a binomial, 3 terms is a trinomial, but all are considered polynomials

Answer 5

A polynomial is a Mathematical Phrase containing terms made of a constant and a variable. It is not only made of one term because it may be 2 or perhaps maybe 3.

Answer 6

a polynomial in mathematics is an equation of degree more than 2.
A 2 degree equation is called a binomial,
eg: ax^2+bx+c=0;is an equation wiht highest power 2,hence its order is 2 and is a binomial.
where a,b,c are positive constants and a not equal to 0
A polynomial looks like
(a0)x^n+(a1)x^(n-1)+(a2)x^(n-2)........+(aN)

where a0,a1,a2,.....aN ----- are constants while x is the variable.a0 not equal to zero.The above equation is a general equation of order n.

Answer 7

It's a number or expression that has two or more terms. A bi-nomial has two terms. These terms are separated by (+) or (-). For example a+2b-4c-6x+10 is a polynomial.

Answer 8

Polynominals is an mathematical expression is the use of numbers.

a polynominal with one term is called a monomials

example
7x²
9
-5a²b²

a polynominal with two terms is called a binominals

Example

3x -5
5a² + 7bc
-6x² +5

a polynominal with three terms is called a Trinominals

Example

2x² - 5x + 9
5x²- 7² + 6
3x+ 5x + 7

Answer 9

polynomial?well...an equation with more than 2 terms.

Answer 10

In science, people used to name things based on how they looked. They had multiple names. (All in latin) You could have a tree who's scientific name is 15 "names" long. In today's world, we use binomials. Like Homo sapiens. Hope that helps.
