Polynomials are mathematical expressions consisting of variables (also called indeterminates) and coefficients, that involve only the operations of addition, subtraction, and multiplication, and non-negative integer exponents of variables. A polynomial is typically written in the form:

a_n * x^n + a_(n-1) * x^(n-1) + ... + a_1 * x + a_0

where a_n, a_(n-1), ..., a_1, a_0 are coefficients, x is the variable, and n is a non-negative integer representing the degree of the polynomial. The degree of a polynomial is the highest power of the variable x that appears in the expression.

Polynomials can be classified based on their degree. A polynomial of degree 0 is called a constant polynomial, a polynomial of degree 1 is called a linear polynomial, a polynomial of degree 2 is called a quadratic polynomial, and a polynomial of degree 3 is called a cubic polynomial. Polynomials of degree 4 or higher are called higher-degree polynomials.

Polynomials can also be classified based on the number of variables they contain. A polynomial with one variable is called a univariate polynomial, and a polynomial with more than one variable is called a multivariate polynomial.

Polynomials are fundamental in mathematics and have numerous applications in various fields, including physics, engineering, and computer science. They are used to model real-world phenomena, solve equations, and analyze data. Polynomials also play a crucial role in the study of algebra, calculus, and other branches of mathematics.
