## Solving (x+2)(x-2)

The expression (x+2)(x-2) is a product of two binomials, which can be simplified using the **difference of squares** pattern.

### Understanding the Difference of Squares

The difference of squares pattern states that:

**(a + b)(a - b) = a² - b²**

In our case, a = x and b = 2. Applying the pattern, we get:

**(x + 2)(x - 2) = x² - 2²**

### Simplifying the Expression

Simplifying further:

**x² - 2² = x² - 4**

Therefore, the simplified form of (x+2)(x-2) is **x² - 4**.

### Key Points

- The difference of squares pattern is a useful tool for simplifying expressions with two binomials where the only difference is the sign between the terms.
- Recognizing this pattern can save time and effort in solving algebraic problems.
