$- 4 A \sin (2 x) - 4 A x \cos (2 x) + 4 B \cos (2 x) - 4 B x \sin (2 x) + 4 A x \cos (2 x) + 4 B x \sin (2 x) + 4 C$

Step 1

Add $- 4 A x \cos (2 x)$ and $4 A x \cos (2 x)$ .

$- 4 A \sin (2 x) + 4 B \cos (2 x) - 4 B x \sin (2 x) + 0 + 4 B x \sin (2 x) + 4 C$

Step 2

Add $- 4 A \sin (2 x) + 4 B \cos (2 x) - 4 B x \sin (2 x)$ and $0$ .

$- 4 A \sin (2 x) + 4 B \cos (2 x) - 4 B x \sin (2 x) + 4 B x \sin (2 x) + 4 C$

Step 3

Add $- 4 B x \sin (2 x)$ and $4 B x \sin (2 x)$ .

$- 4 A \sin (2 x) + 4 B \cos (2 x) + 0 + 4 C$

Step 4

Add $- 4 A \sin (2 x) + 4 B \cos (2 x)$ and $0$ .

$- 4 A \sin (2 x) + 4 B \cos (2 x) + 4 C$
