Find the product of (4a + 3) (4a - 3) : ___.
- A 12a2 - 9
- B 8a2 + 9
- C 16a2 - 9
- D 16a2 + 2a - 9
That's Correct!
It's Wrong!
The given expression is a product of two binomials. To find the product, we can use the formula for the difference of squares, which states that (a + b)(a - b) = a^2 - b^2. In this case, a = 4a and b = 3. Substituting these values into the formula, we get (4a + 3)(4a - 3) = (4a)^2 - 3^2 = 16a^2 - 9. Therefore, the correct answer is 16a^2 - 9.
