Polynomials are algebraic expressions that include real numbers and variables. Division and square roots cannot be involved in the variables. The variables can only include addition, subtraction and multiplication.
Polynomials contain more than one term. Polynomials are the sums of monomials.
A monomial has one term: 5y or -8x2 or 3.
A binomial has two terms: -3x2 2, or 9y - 2y2
The degree of the term is the exponent of the variable: 3x2 has a degree of 2.
When the variable does not have an exponent - always understand that there's a '1' e.g., 1x
8x2 3x -2 Polynomial
8x-3 7y -2 NOT a Polynomial The exponent is negative.
9x2 8x -2/3 NOT a Polynomial Cannot have division.
