Factoring (x² - 4)(x² + 6x + 9)
This expression involves factoring two separate quadratic expressions. Let's break it down step by step:
Factoring (x² - 4)
This is a difference of squares. We can factor it as:
(x² - 4) = (x - 2)(x + 2)
Factoring (x² + 6x + 9)
This is a perfect square trinomial. We can factor it as:
(x² + 6x + 9) = (x + 3)²
Combining the Factors
Now, we can substitute the factored expressions back into the original expression:
(x² - 4)(x² + 6x + 9) = (x - 2)(x + 2)(x + 3)²
Therefore, the completely factored form of (x² - 4)(x² + 6x + 9) is (x - 2)(x + 2)(x + 3)².
