Simplifying (2x + 3)(2x - 3)
The expression (2x + 3)(2x - 3) represents the product of two binomials. We can simplify it using the difference of squares pattern.
The Difference of Squares Pattern
The difference of squares pattern states that:
(a + b)(a - b) = a² - b²
Applying the Pattern
-
Identify 'a' and 'b':
- In our expression, a = 2x and b = 3.
-
Substitute into the pattern:
- (2x + 3)(2x - 3) = (2x)² - (3)²
-
Simplify:
- (2x)² - (3)² = 4x² - 9
Conclusion
Therefore, the simplified form of (2x + 3)(2x - 3) is 4x² - 9. This process demonstrates how recognizing common algebraic patterns can help simplify expressions quickly and efficiently.
