Study Notes
Algebraic Expressions
- An algebraic expression is a mathematical phrase that combines variables, constants, and mathematical operations.
- Examples of algebraic expressions include 2x + 3, x^2 - 4, and 5x - 2.
Factoring Algebraic Expressions
- The process of breaking down an algebraic expression into its factors is called factoring.
- Factoring involves expressing an algebraic expression as a product of simpler expressions, called factors.
Factors of Algebraic Expressions
- A factor of an algebraic expression is an expression that divides the original expression exactly without leaving a remainder.
- 3 is a factor of the algebraic expression '3x + 6', as 3(3x + 2) = 3x + 6.
