Expanding and Simplifying the Expression (2+7x)(2-7x)
This expression represents the product of two binomials. We can simplify it by using the difference of squares pattern.
Difference of Squares Pattern
The difference of squares pattern states:
(a + b)(a - b) = a² - b²
Applying the Pattern
Let's apply this pattern to our expression:
-
Identify 'a' and 'b':
- a = 2
- b = 7x
-
Substitute into the pattern:
- (2 + 7x)(2 - 7x) = 2² - (7x)²
-
Simplify:
- 2² - (7x)² = 4 - 49x²
Final Result
Therefore, the simplified form of (2 + 7x)(2 - 7x) is 4 - 49x².
