• ### Ascending Order

An ordering of terms of a polynomial in which the degree of each term is at least as large as the degree of the preceding term.

• ### Binomial

A polynomial with two terms.

• ### Common Factor

A factor of all the terms in an expression.

• ### Degree

of a monomial. The sum of the exponents of its variables. of a polynomial. The largest of the degrees of its individual terms.

• ### Descending Order

An ordering of terms of a polynomial in which the degree of each term is no larger than the degree of the preceding term.

• ### Difference of Squares

The binomial which is the product of the sum and difference of the same two terms, i.e. one of the form a2 - b2.

• ### Factor

A factor is integer, variable, or polynomial that can be multiplied by a constant, an integer, or a polynomial to produce the given expression. To factor means to separate an expression into simpler factors. For instance,

 a2 -2ab + b2 = (a - b)(a - b) ax2 + abx + ac = a(x2 + bx + c)

The coefficient of the first term of a polynomial written in descending order.

• ### Monomial

• ### Perfect Square Trinomial

The square of a binomial; has the form a2 +2ab + b2.

• ### Polynomial

A monomial or the sum or difference of several monomials.

• ### Trinomial

A polynomial with three terms.
