Answer:

A - Algebraic Expression

In mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations. For example, 3x² − 2xy + c is an algebraic expression.

B - Constant

In mathematics, a constant term is a term in an algebraic expression that has a value that is constant or cannot change, because it does not contain any modifiable variables

C - Variable

Variable, In algebra, a symbol (usually a letter) standing in for an unknown numerical value in an equation. Commonly used variables include x and y (real-number unknowns), z (complex-number unknowns), t (time), r (radius), and s (arc length).

D - Monomial

A monomial is an expression in algebra that contains one term, like 3xy. Any number, all by itself, is a monomial, like 5 or 2,700. ... A monomial can also be a variable, like m or b.

E - Binomial

In Algebra, a binomial expression is an expression containing two terms joined by either addition or subtraction sign. For instance, (x + y) and (2 – x) are examples of binomial expressions. Sometimes, we may need to expand binomial expressions as shown below. (a + b)0 = 1.

F - Trinomial

The relationship between these terms may be sums or difference. You call an expression with a single term a monomial, an expression with two terms is a binomial, and an expression with three terms is a trinomial. An expression with more than three terms is named simply by its number of terms.
