Key Concepts

Polynomial

A polynomial is an expression made up of variables and coefficients, involving only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. In the context of multi-variable expressions, each term is a product of a coefficient and variables raised to some powers, and the overall polynomial sums these terms.

Degree of a Polynomial

The degree of a polynomial is determined by the term with the highest sum of exponents when all terms are considered. In a multivariable polynomial, each term has a degree calculated by summing the exponents of all the variables in that term, and the overall polynomial’s degree is the maximum of these sums.

Leading Coefficient

The leading coefficient is the coefficient of the term that has the highest degree in the polynomial. This term, often referred to as the leading term, influences the polynomial’s behavior especially for large values of the variables, and identifying it is key in understanding the growth and end behavior of the function.
