$2 \tan^{2} (x) \sec^{2} (x) - \sec^{4} (x)$

Step 1

Factor $\sec^{2} (x)$ out of $2 \tan^{2} (x) \sec^{2} (x)$ .

$\sec^{2} (x) (2 \tan^{2} (x)) - \sec^{4} (x)$

Step 2

Factor $\sec^{2} (x)$ out of $- \sec^{4} (x)$ .

$\sec^{2} (x) (2 \tan^{2} (x)) + \sec^{2} (x) (- \sec^{2} (x))$

Step 3

Factor $\sec^{2} (x)$ out of $\sec^{2} (x) (2 \tan^{2} (x)) + \sec^{2} (x) (- \sec^{2} (x))$ .

$\sec^{2} (x) (2 \tan^{2} (x) - \sec^{2} (x))$
