**What Is A Polynomial** – The word polynomial is made up of two words, “poly” and “nominal”, meaning many terms. It is used to represent expressions in mathematics. Thus, an apolynomial expression is an expression that contains at least two numbers and contains at least one arithmetic operation.

A polynomial is made up of terms and each term has a coefficient, while an expression is an expression that contains at least two numbers and contains at least one arithmetic operation. Expressions that meet the criterion of polynomiality are polynomial expressions. Let’s look at the following examples to see if they are polygons or not.

## What Is A Polynomial

+ 3√x+ 1 is not a polynomial expression because the variable has a partial exponent, i.e. 1/2, which is a non-integer value; while for the second expression x

## Which Of The Following Is A Polynomial?

+ √3 x + 1, the fractional power is at 1/2 constant which in this case is 3, so it is a polynomial expression.

A monomial consists of only one term with the condition that this term must be non-zero. Examples: 6x, 7x

A binomial is a polynomial consisting of two terms. It is written as the sum or difference of two or more monomials. Examples: 2×4 + 8x, 8y

. Here, the highest exponent according to the polynomial expression is 3. Therefore, the degree of the polynomial expression is 3. Observe the following expression.

+ 6. We follow the above steps, with an additional step of adding powers of the various variables to the given terms. And so the degree of the polynomial is 6. This is because in 3x

, the exponent values of x and y are 2 and 4 respectively. If we add them, we get 6. Therefore, the degree of the multivariate polynomial expression is 6. Observe the following polynomial that shows how its degree is considered to be 9 .

Terms with similar variables are combined with arithmetic operations to simplify calculations. For example, we simplify the polynomial expression: 5x

FOIL (First, Outer, Inner, Last) technique is used for arithmetic operations of multiplication. Each step uses the distributive property. ‘For’ means multiplying the terms that come first in each binomial. Then ‘outer’ means multiplying the outer terms in the product, followed by the ‘inner’ terms, and then the ‘last’ terms. For example, to simplify the given polynomial expression, we use the FOIL technique, (x – 4) (x + 3). The expression can be rewritten, x (x + 3) – 4 (x + 3). Multiplying the outer terms we get, x

## Basic About Polynomials

Any expression that contains variables, constants, and exponents, and is combined using arithmetic operators such as addition, subtraction, multiplication, and division, is a polynomial expression. Polynomial expressions can be classified as monomials, binomials, and trinomials according to the number of terms in the expression.

How can you tell if an expression is polynomial? We need to check the following points to know if an expression is polynomial:

The terms of polynomials are the parts of the expression that are separated by “+” or “-” signs. For example, in a polynomial, say, 3x

A polynomial of zero is a polynomial with degree 0, while the zero of the polynomial is the value (or values) of the variable for which the entire polynomial can be zero. In this form: 𝑓 𝑥 = 𝑎 𝑛 𝑥 𝑥 + 𝑎 𝑛−1 𝑥 𝑛−1 + ⋯ 𝑎 1 𝑥+ 𝑎 0 . Coefficients are real numbers. Exponents are non-negative numbers. The domain of a function is the set of all real numbers.

Properties of the power function A positive EVEN integer with an even function The graph is parallel to the y-axis. The domain is the set of all real numbers. The range is the sum of all non-negative real numbers. A graph always has points (0, 0), (-1, 1), and (1, 1). The graph will be flattened for x-values between -1 and 1.

If f(r) = 0 and r is a real number, then r is a real zero of the function. A real zero is a real zero of a function equal to r. r is an x-intercept of the graph of the function. (x – r) is an element of the function. r is a solution of the function f(x) = 0.

The number of times a factor (m) of a function is repeated is called its multiplicity (zero multiple of m). The graph of a zero multiplicative function of an even number touches the x-axis, but does not cross it. The graph of an odd-numbered zero-multiplier function crosses the x-axis, but will flatten if the number is greater than 1.

It is also a general way to represent different types of polygons, i.e. coefficients (a_n, a_, a_, …, a_0) and powers (n ) can have numerical values depending on what type of polynomials do they represent? .

The roots of a zero or nth degree polynomial are the values that make the polynomial value ‘0’.

Zeros are defined as those ( alpha, beta, … , n ) values that (x)(P(x) in (x)(P(x)) will return ‘0’ when replaced.

The zeros of any polynomial can be found using its graphical representation. The number of times the graph intersects the x-axis is equal to the number of distinct zeros of the polygon.

Here the graph crosses the x-axis 3 times, which means that the polynomial will have 3 distinct zeros at (x = ) respectively.
