1. Binomial: A binomial is a polynomial with two terms. This means that it consists of two monomials added or subtracted together. For example, "3x + 5" and "2xy - 4z" are both binomials.

2. Degree of Monomial: The degree of a monomial is the sum of the exponents of all its variables. In other words, it represents the highest power to which any variable is raised in the monomial. For example, in the monomial "5x^2y^3", the degree is 2+3 = 5.

3. Monomial: A monomial is an algebraic expression that is a number, a variable, or a product of a number and one or more variables. It can have non-negative integer exponents. For example, "3x", "5y^2", and "7" are all monomials.

4. Perfect-Square Trinomial: A perfect-square trinomial is a trinomial that can be factored into the square of a binomial. In other words, it is the product of two identical binomial factors. For example, (x+2)^2 or (2x-3)^2 are both perfect-square trinomials.

5. Standard Form of Polynomial: The standard form of a polynomial is when the terms are ordered from highest degree to lowest degree, with no like terms. In other words, the terms decrease in degree from left to right and any similar terms are combined. For example, the standard form of the polynomial "4x^3 + 2x^2 - 3x + 1" is "4x^3 + 2x^2 - 3x + 1" itself. It is important to note that the standard form of a polynomial is not unique, as different equivalent forms can exist.
