Study Notes
Difference of Two Squares
- This identity applies to expressions with two squared terms subtracted.
- For example, x² - 9 can be rewritten as (x)² - (3)² .
- The expression can be factored into two binomials: one with addition and one with subtraction.
- For instance, x² - 9 factors to (x + 3)(x - 3) .
- This identity is used to simplify algebraic expressions.
- It aids in solving equations through factoring.
- It's applicable in coordinate geometry and problem-solving.
- Recognize perfect squares when using this identity (e.g., 25x²).
- Ensure subtraction exists between the squared terms.
