Simplifying Algebraic Expressions
Simplifying means rewriting an expression in its simplest form-combining like terms, removing parentheses, and reducing coefficients where possible.
Steps to Simplify:
- Remove parentheses: Apply the distributive property if needed:
- Combine like terms: Add or subtract terms with the same variable and exponent.
- Order terms: Arrange according to variable or degree (often highest to lowest).
- Combine like terms (
2x + 3x - x = 4x) - Combine constants (
4 + 2 = 6) - Write final answer:
- Only combine terms with the same variables and exponents.
- Careful with subtraction and negative signs!
- Use distributive property and combine like terms to simplify.
- Final form has no parentheses and all like terms are merged.
Example: 2(x + 3) becomes 2x + 6
Example: 3x + 2x becomes 5x
Example
Simplify: 2x + 4 + 3x - x + 2
4x + 6
