### Key Terms

binomial
A binomial is a polynomial with exactly two terms.
degree of a constant
The degree of a constant is $00$.
degree of a polynomial
The degree of a polynomial is the highest degree of all its terms.
degree of a term
The degree of a term of a polynomial is the exponent of its variable.
greatest common factor
The greatest common factor (GCF) of two or more expressions is the largest expression that is a factor of all the expressions.
monomial
A term of the form $axmaxm$, where $aa$ is a constant and $mm$ is a whole number, is called a monomial.
negative exponent
If $nn$ is a positive integer and $a≠0a≠0$, then $a−n=1ana−n=1an$.
polynomial
A polynomial is a monomial, or two or more monomials, combined by addition or subtraction.
scientific notation
A number expressed in scientific notation when it is of the form $a×10n,a×10n,$ where $a≥1a≥1$ and $a<10,a<10,$ and $nn$ is an integer.
trinomial
A trinomial is a polynomial with exactly three terms.
zero exponent
If $aa$ is a non-zero number, then $a0=1a0=1$. Any nonzero number raised to the zero power is 1.
