X2 - 16, is the answer. The first one.

x^2 - 16 = (x)^2 - 4^2, difference of two squares :)

The difference of two squares is of the form:

(a^2-b^2)

I believe that they might just want you to select

(x^2-16) which factors to (x-4)(x+4)

But there is nothing mathematically incorrect in doing the same for:

(x^2-8) which factors to (x-√8)(x+√8)

I drew a picture!!

Maybe you didn't.
.
I like to picture things though.

Ok, a rectangle cut in half.
.
Ok, by definition of "half," just multiply the number of rectangles by 2.
.
1 x 2 = 2 after cutting the brownies in half.
.
2 x 2 = 4 after cutting it in half again.
.
4 rectangles now!!
.
Doing it the other way... pretend you are starting over from scratch.
.
A new batch of brownies!
.
But still pay attention to what you already cut.
.
Cut down the middle the other direction.
.
What's 4 x 2?
.
8.
.
Now, finally, we multiply the half of the half brownies.
.
What's 8 x 2?
.
16.
.
16 slices.
