Answer:

Option B, Spencer did not factor the polynomial completely; 16x^2−1 can be factored over the integers.

Step-by-step explanation:

<u>Step 1:  Factor</u>

256x^4y^2−y^2

y^2(256x^4 - 1)

y^2(16x^2 - 1)(16x^2 + 1)

<em>y^2(</em><em>4x + 1)(4x - 1</em><em>)(16x^2 + 1)</em>

<em />

Answer:  Option B, Spencer did not factor the polynomial completely; 16x^2−1 can be factored over the integers.
