Algebraic Expression

Concept

Algebraic Expression

An algebraic expression is a valid combination of numbers, variables, and mathematical operations. For example, in the expression 2x+3,2x+3, the variable xx is being multiplied by its coefficient 2;2; then, this product is added to the constant 3.3.

Algebraic expressions come in many forms; they can be monomials, like the 2x2x in the binomial expression above. In a polynomial, each monomial separated by a ++ or - sign is called a term. -3x2+2x1\begin{gathered} \text{-}3x^2+2x-1 \end{gathered} An entire polynomial, like the trinomial above, is also called an algebraic expression. However, an expression that only contains constants is called a numerical or numeric expression.
