Polynomial Formula

Polynomial Formula

An algebraic expression known as a polynomial has variables with non-negative powers. A polynomial function is an equation that has a single independent variable and allows the variable to appear several times with varying exponent values. Any expression with more than two algebraic terms is referred to as a polynomial expression. As the name implies, a polynomial is a monomial or binomial that has been added repeatedly.

The form “polynomial = 0” characterises all polynomial equations. It has the algebraic Polynomial Formula p(x) = an xn + a – 1 xn – 1 +… + a1 x + a0 = 0, where,

All of the coefficients, an, a – 1,…, a1, a0, are real numbers.

The variable is ‘x’.

In terms of variables, p(x) stands for polynomial x.

Since it is the highest exponent and a non-negative integer, “n” is the degree of p. (x).

Polynomial Formula

Polynomial Formula, in which the relationship between numbers and variables is explained in a pattern, is one of the important mathematical topics. Numerous equations are created in Mathematics using algebraic expressions. Algebraic equations can also take the form of polynomial equations. In a polynomial, the independent variable may appear more than once. These several instances of the variable are separated by addition, subtraction, and multiplication operations. The highest degree of the exponent in the equation is referred to as the Polynomial Formula degree. It is also known as the polynomial equation’s order. 

What is a Polynomial?

One of the fundamental concepts of algebra in mathematics is a polynomial equation. Students will be able to perform significantly better on examinations and will also have a solid foundation for their higher education if they have a clear understanding of how to handle a polynomial issue. Numbers and variables are used in the Polynomial Formula. An algebraic equation can also take the form of a polynomial equation. The distinction between a polynomial and a polynomial equation is negligible. Expressions are polynomials, but expressions that equal zero are Polynomial Formula.

The Polynomial Formula can be written as the sum of a finite number of terms, where each term is the product of one or more variables raised to a positive integer and a constant coefficient. It is an expression that can only have addition, subtraction, and multiplication operations as well as non-negative integer exponents (or powers). Simply expressed, an equation is only a polynomial if it can be written without division. Additionally, if even one term in an expression has a negative exponent, the expression is not categorised as a polynomial (or power). If even one of the terms in an expression contains a fraction exponent, the expression is not categorised as a polynomial (or power).

Types of Polynomial

The degree of the polynomial determines the category of the polynomial equation. Polynomial equations can be categorised into four groups for practical purposes.

  1. Equation that is Monomial/Linear

A monomial equation is a polynomial equation with just one variable term. It also goes by the name linear equation. A linear equation has the following algebraic form:

Where an is the coefficient, b is the constant, and the polynomial’s degree is 1, the equation is axe + b=0.


2x + 10 = 0

x – 5 = 0

  1. Equation of Binomial/Quadratic type

A binomial equation is a polynomial with two variable terms. Another name for it is a quadratic equation. A quadratic equation has the following algebraic form:

The equation is written as ax2 + bx + c = 0, where a and b are coefficients, c is a constant, and the polynomial’s degree is 2.


2×2 + 2x + 2 = 0

x2 – 4=0

  1. Cubic/Trinomial Equation

A trinomial equation is a polynomial with three variable terms. Another name for it is a cubic equation. A quadratic equation has the following algebraic form:

The equation is: ax3 + bx2 + cx + d = 0, where a, b, and c are coefficients, d is a constant, and the polynomial’s degree is 3.


x3 + 2×2 + 3x – 5 = 0

2×3 – 5x = 0

FAQs (Frequently Asked Questions)

1. How can one determine whether a Polynomial Formula is a polynomial?

The algebraic expression must have all of its exponents be non-negative integers in order for it to be a polynomial. As a general rule, an algebraic expression isn’t a polynomial if it contains a radical.

2. How is a function classified as a polynomial?

In an equation such as the quadratic equation, cubic equation, etc., a polynomial function is a function that only uses non-negative integer powers or only positive integer exponents of a variable.
