Answer:

(x + 2) (x - 2)

Step-by-step explanation:

Given the quadratic expression, x² - 4:

Use the <u>Difference of squares</u> factoring formula:

u² - v² = (u + v)(u - v)

Determine what are possible factors that could have a product of -4:

Since -2 × 2 = -4, these can be used as factors.

Therefore, the factors of the quadratic expression, x² - 4 are:

(x + 2) (x - 2)
