Answer

Then simplify the expression, we get 6sin⁡(x)−8sin3⁡(x)

Steps

Step 1 ：Using the triple-angle formula, we can rewrite sin⁡(3x) as 3sin⁡(x)−4sin3⁡(x)

Step 2 ：Substitute the above expression back into the original expression, we get 2(3sin⁡(x)−4sin3⁡(x))

Step 3 ：Then simplify the expression, we get 6sin⁡(x)−8sin3⁡(x)
