| binomial | A polynomial with exactly two terms, such as 5y2 – 4x and x5 + 6. |
| coefficient | A number that multiplies a variable. |
| constant | A symbol that represents a quantity that cannot change. It can be a number, letter or a symbol. |
| degree | The value of an exponent. |
| like terms | Terms that contain the same variables raised to the same powers. For example, 3x and −8x are like terms, as are 8xy2 and 0.5xy2. |
| monomial | A polynomial with exactly one term. 4x, −5y2, and 6 are all examples of monomials. |
| polynomial | A monomial or the sum or difference of two or more monomials. |
| term | A number or product of a number and variables raised to powers. 4x, −5y2, 6, and x3y4 are all examples of terms. |
| trinomial | A polynomial with exactly three terms, such as 5y2 – 4y + 4 and x2 + 2xy +y2. |
