Question

Choose the correct product of (8x − 4)(8x + 4). (1 point) 64x2 − 16 64x2 + 16 64x2 − 64x + 16 64x2 + 64x + 16

Answer 1

Answer:

The correct answer is "$64*x^2 - 16$".

Step-by-step explanation:

The product $(8*x - 4)*(8*x + 4)$ is a notable product, which happens when we have the product of the sum of two values with the subtraction of these same two values. In cases like this the answer will always be the first term squared minus the second term squared, therefore we have:

$(8*x - 4)*(8*x + 4) = 64*x^2 - 16$

The correct answer is "$64*x^2 - 16$".
