$2 \sin (x) \cos (x) - \sin (x)$

Step 1

Factor $\sin (x)$ out of $2 \sin (x) \cos (x)$ .

$\sin (x) (2 \cos (x)) - \sin (x)$

Step 2

Factor $\sin (x)$ out of $- \sin (x)$ .

$\sin (x) (2 \cos (x)) + \sin (x) \cdot - 1$

Step 3

Factor $\sin (x)$ out of $\sin (x) (2 \cos (x)) + \sin (x) \cdot - 1$ .

$\sin (x) (2 \cos (x) - 1)$
