See a solution process below:

First, factor out a common term from each term in the expression:

$(2 xx x^4y^2) - (2 xx 16) => 2(x^4y^2 - 16)$

Now, use this rule for quadratics to factor the term on the right:

$color(red)(x)^2 - color(blue)(y)^2 = (color(red)(x) + color(blue)(y))(color(red)(x) - color(blue)(y))$

$2(x^4y^2 - 16) => 2(x^2y - 4)(x^2y + 4)$
