So the answer is
(<span>x^2 plus or minus 6)(x^2 plus or minus 6)
an easy way to do this is to only look at plus or minus 6
x^4 <u><em>- 12</em></u>x^2 + <u><em>36 (-12 and 36)
</em></u><em />
<u><em /></u>6 x 6 = 36
<em />6 + 6 </span>≠ -12 (x^2 + 6)(x^2 + 6) is incorrect
<span><u><em>
</em></u><em><u /></em><u />6 x -6 </span>≠ 36
<span><em />6 + -6 </span>≠ -12 (x^2 - 6)(x^2 + 6) is incorrect
<span><em /><em>
</em><em />-6 x -6 = 36
<em />-6 + -6 = -12 </span><span>(x^2 - 6)(x^2 - 6) is correct
</span><u><em>
the answer is (1)
</em></u>
Most likely to be letter C
