How are Algebraic Expressions Formed?
An algebraic expression is formed from variables and constants using different operations.
It is an expression that is made up of variables and constants along with algebraic operations such as addition, subtraction, etc.. these Expressions are made up of terms. Algebraic expressions are the equations when the operations such as addition, subtraction, multiplication, division, etc. are operated upon any variable.
A combination of terms by the operations such as addition, subtraction, multiplication, division, etc is termed as an algebraic expression (or) a variable expression.
Example: If 2x2 + 3xy + 4x + 7 is an algebraic expression.
Terms of Algebraic Equation: 2x2, 3xy, 4x, and 7
Coefficient of Term: 2 is the coefficient of x2, 3 is coefficient of xy, 4 is coefficient of x
Constant term: 7
Variables: Here x, y are variables
Like terms: 4x and 3x
Unlike terms: 2x and 4y

How are Algebraic Expressions Formed?
Basic concept of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are termed here as variables. this expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is termed a coefficient.
An idea of expressing numbers using letters or alphabets without specifying their actual values is termed an algebraic expression.
