# Describe algebraic expressions

The given expression is x2 + 56x + 768. Algebra is an important subject which is an essential part of mathematics. It deals with variables (quantities that are able to change) and constants (quantities that are fixed). In algebra, we also study about algebraic operators which are – addition, subtraction, division, multiplication and exponentiation. We’re going to learn about algebraic expressions in this page The algebraic expressions have the variables and the constants. The algebraic expressions are the finite combination of the symbols that are formed according to the rules of the context. In other words, an algebraic expression is the combination of constants and variables which are interrelated with the help of algebraic operators. The algebra is an expression which is used to designate the value for the given values in the expression. The expression might be depending on the values assigned to the values assigned in the expression. The expression is the syntactic concept in the algebra Few examples of algebraic expressions are -(1) 3 m n$^2$(2) 4a + 9 b(3) $fracxy4z$(4) x + 4y + zAlgebraic expressions are of different types, such as -(1) Rational Expression(2) Irrational Expression(3) Logarithmic Expression(4) Exponential ExpressionLet us understand more about algebraic expression. . . . . . . . . .
