#### Answer

$2x(x-6)(x+6)$

#### Work Step by Step

RECALL:
A difference of two squares can be factored using the formula:
$a^2-b^2=(a-b)(a+b)$
Factor out the greatest common factor, $2x$, to obtain:
$=2x(x^2-36)
\\=2x(x^2-6^2)$
The binomial is a difference of two squares.
Factor the given difference of two squares using the formula above with $a=x$ and $b=6$ to obtain:
$=2x(x-6)(x+6)$
