This is the Algebra 2 glossary. Here are all the terms you need to know to combat the mathematical world.

# A

**Axes**: The two lines on a coordinate plane that run perpendicular to each other that act as a guidance to finding a point or identifying functions

# B

# C

**Constant**: A number with no variable that never changes

**Coordinate**: A location on a plane described by the *x* location and *y* location of the axes

# D

**Degree**: The sum of the exponential values of a term. When referring to polynomials, it is the greatest sum of the exponential values of all the terms.

**Distribution**: The process of multiplying a term or collection of terms by a group of terms.

# E

**Equation**: A relation of two equivalent expressions

**Expanding**: The process of bringing a form of something into either its most basic form, standard form, or form that is easily understood or visually better

**Expression**: Constants, coefficients, and variables bound together by mathematical operations with no comparison or relation

# F

**Factoring**: The process of bringing a polynomial into a form where the roots or solutions are easily visible

**FOIL**: An acronym used to multiply a binomial by a binomial. You multiply the firsts, the outers, the inners, and the lasts.

**Function**: An equation of two variables where one defines the other after a system of operations. In a function, the independent value cannot have more than one dependent value.

# G

# H

# I

**Inequality**: A relation of two expressions in terms of greater than, less than, greater than or equal to, or less than or equal to.

**Intersection**: The point where two lines converge. Famous intersections are the Origin, intercepts of a function, and the solution to a system of equations.

**Inverse**: The opposite of something as to yield 0 or 1. When pertaining to matrices, the inverse yields the identity matrix.

# J

# K

# L

**Leading Coefficient**: The coefficient of the term of highest degree in a polynomial.

**Linear Function**: A function with a maximum polynomial degree of one. A linear function has a constant rate and looks like a straight line when graphed.

**Long Division**: The process of dividing that uses a system of dividing smaller parts cumulatively.

# M

**Matrix**: A rectangular array of information

**Monomial**: A term

# N

# O

**Origin**: The point where the axes intersect. The coordinate for this point is (0,0)

# P

**Polynomial**: A collection of terms bound by addition or subtraction so that there are no negative, fractional, or variable exponential degrees.

# Q

**Quadrant**: A section of the coordinate plane described by the signs of the coordinates it holds

# R

# S

**Slope**: The rate of which a function increases or decreases. Slope is constant in linear functions, but non-linear functions have changing slopes.

**Synthetic Division**: A process of doing long division much quicker and in a visually easy fashion.

# T

**Term**: An expression bound by multiplication and division. A term does not contain any addition or subtraction.

# U

# V

**Variable**: An unknown value dictated by a letter or symbol.
