# Choose the correct product of (8x - 4)(8x + 4).

64x^{2} - 16, 64x^{2} + 16, 64x^{2} - 64x + 16, 64x^{2} + 64x + 16

**Solution:**

We will use the algebraic identity to find the correct product of (8x - 4)(8x + 4).

The equation is in the form (a + b)(a - b).

Therefore, we will use the algebraic identity

a^{2} - b^{2} = (a + b)(a - b)

Where a = 8x and b = 4

Thus, the equation (8x - 4)(8x + 4) can be written in the form of (8x)^{2} - (4)^{2}.

On simplifying it we get,

(8x - 4)(8x + 4)= 64x^{2} - 16

## Choose the correct product of (8x - 4)(8x + 4).

**Summary:**

Using the algebraic identity a^{2} - b^{2} = (a + b)(a - b). The correct product of (8x - 4)(8x + 4) is 64x^{2} - 16.
