Prime number

A whole number with exactly two factors, 1 and itself

Prime factorization

writing a number as its prime number factors

GCF- Greatest common factor

LCM - Lowest common multiple

Perfect Square

A number made by squaring (power of two) a whole number.

Perfect Cube

A number made by cubing (power of three) a whole number.

Binomial

A polynomial with two terms

Trinomial

A polynomial with three terms

Polynomial

An expression that can have constants (like 4), variables (like x or y) and exponents (like the 2 in y2), that can be combined using addition, subtraction, multiplication and division, but: • no division by a variable. • a variable's exponents can only be 0,1,2,3,... etc. • it can't have an infinite number of terms.

Variable

A symbol for a number we don't know yet. It is usually a letter like x or y.

Coefficient

A number used to multiply a variable

Perfect Square Trinomial

A trinomial of the form a^2 +2ab + b^2; it can be factored as (a + b) ^2

Difference of Squares

A binomial of the form a^2 - b^2; it can be factored as (a-b) (a+b)

Simplify

Changing something into it's most factored form; Simplest form

Expand
