What is an Algebraic Expression?

An Algebraic Expression is a math phrase made of numbers, letters, and operations (like +, -, ×, ÷). It does NOT have an equals sign (=).

Example: 5x + 3

VARIABLE

Variable

A letter representing an unknown value (e.g., x, y)

COEFFICIENT

Coefficient

The number multiplied by the variable (e.g., 5 in 5x)

CONSTANT

Constant

A fixed number standing alone (e.g., 3 in 5x + 3)

TERM

Term

Parts separated by + or - signs (e.g., 5x and 3)

EXPRESSION 3x + 5

EQUATION 3x + 5 = 20

The equals sign (=) is the ONLY difference! An equation can be solved, an expression cannot.

Let's Break It Down

Expression: 4x² + 7x - 3

1st Term: 4x² → Coefficient is 4, Variable is x

2nd Term: 7x → Coefficient is 7, Variable is x

3rd Term: -3 → This is the Constant

Total of 3 terms in this expression!
