Using the double angle formula for sine, we have:
$$-16\sin(x)\cos(x) = -8\sin(2x) = \boxed{-8\sin(2x)}$$

Use a Double Angle Formula to Rewrite the Following Expression −16sin⁡(x)cos⁡(x)- 16 \sin ( x ) \cos ( x )−16sin(x)cos(x)

Use a Double Angle Formula to Rewrite the Following Expression $- 16 \sin ( x ) \cos ( x )$
