## Basic Definitions

**Term definition**– A term is a constant or product of constant and one or more variables- Degree of term is exponent of its variable, example, in 4b
^{2}, degree of term 4b^{2}is 2

- Degree of term is exponent of its variable, example, in 4b
**Monomial**is of the form ax^{m}where a is constant and m is whole number, so monomial contains only 1 term. Example: 4, 4b^{2}- A monomial or sum and/or difference of monomial is called
**Polynomial**. Example: 4y^{2}– 7y + 2- Degree of polynomial is highest degree of all its terms. In above example degree of polynomial 4y
^{2}– 7y + 2 is 2

- Degree of polynomial is highest degree of all its terms. In above example degree of polynomial 4y
**Binomial**contains 2 terms, example, 3a-7**Trinomial**contains 3 terms, example, x^{2}-5x+6

## Adding, Subtracting, Multiplying Polynomials

- Addition, Subtraction of polynomials involves identifying like terms, then rearranging to get like terms together and then combining like terms
