**binomial**A binomial is a polynomial with exactly two terms.

**degree of a constant**The degree of a constant is 0.

**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 axm, where a is a constant and m is a whole number, is called a monomial.

**negative exponent**If n is a positive integer and a≠0, then a−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, where a≥1 and a<10, and n is an integer.

**trinomial**A trinomial is a polynomial with exactly three terms.

**zero exponent**If a is a non-zero number, then a0=1. Any nonzero number raised to the zero power is 1.
