The factors of (4a^2 - 16) are?
- 4(a - 2)(a + 2)
- 4(a + 2)(a + 2)
- (a - 2)(a - 2)
- None of these
Explanation
To factor the expression:
4a² - 16
First, factor out the greatest common factor (GCF), which is 4:
4(a² - 4)
Then, recognize the difference of squares pattern:
a² - 4 = (a - 2)(a + 2)
So, the factored form is:
4(a - 2)(a + 2)
