Answer 1

Answer? the answer choices are in letters

Answer 2

To factor the polynomial \(16x^8 - 49x^2\), we can recognize that this expression follows the pattern of the difference of squares:

\[
a^2 - b^2 = (a - b)(a + b)
\]

In this case, we can rewrite \(16x^8\) and \(49x^2\) as:

\[
16x^8 = (4x^4)^2 \quad \text{and} \quad 49x^2 = (7x)^2
\]

Therefore, we can express the polynomial as:

\[
(4x^4)^2 - (7x)^2
\]

Now we can apply the difference of squares formula:

\[
(4x^4 - 7x)(4x^4 + 7x)
\]

Thus, the polynomial \(16x^8 - 49x^2\) can be factored as:

\[
(4x^4 - 7x)(4x^4 + 7x)
\]

So the correct answer is that the difference of squares pattern can be used to factor \(16x^8 - 49x^2\).

Answer 3

Based on the provided options and the analysis of the polynomial \(16x^8 - 49x^2\), the correct choice is:

**(a - b)(a + b) = a^2 - b^2**

This represents the difference of squares pattern that can be applied to factor the polynomial.
