Multiply. (2n + 2)(2n – 2)
A. 4n2 – 4
B. 4n2 – 4n – 4
C. 4n2 + 2n – 4
D. 4n2 + 4n – 4
B. 4n^2 - 4n - 4
To multiply (2n + 2)(2n - 2), we can use the distributive property.
First, multiply the first terms in each set of parentheses: 2n * 2n = 4n^2.
Next, multiply the outer terms: 2n * -2 = -4n.
Then, multiply the inner terms: 2 * 2n = 4n.
Finally, multiply the last terms: 2 * -2 = -4.
Now, combine the terms: 4n^2 + (-4n) + (4n) + (-4).
Simplifying, we have: 4n^2 - 4.
Therefore, the correct answer is A. 4n^2 - 4.
