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!
