Step 1.1

Factor $2 y^{4}$ out of $2 x^{4} y^{4}$ .

$2 y^{4} (x^{4}) - 2 y^{4}$

Step 1.2

Factor $2 y^{4}$ out of $- 2 y^{4}$ .

$2 y^{4} (x^{4}) + 2 y^{4} (- 1)$

Step 1.3

Factor $2 y^{4}$ out of $2 y^{4} (x^{4}) + 2 y^{4} (- 1)$ .

$2 y^{4} (x^{4} - 1)$

Step 2

Rewrite $x^{4}$ as ${(x^{2})}^{2}$ .

$2 y^{4} ({(x^{2})}^{2} - 1)$

Step 3

Rewrite $1$ as $1^{2}$ .

$2 y^{4} ({(x^{2})}^{2} - 1^{2})$

Step 4

Since both terms are perfect squares, factor using the difference of squares formula, $a^{2} - b^{2} = (a + b) (a - b)$ where $a = x^{2}$ and $b = 1$ .

$2 y^{4} ((x^{2} + 1) (x^{2} - 1))$
