drek231 [11]

Answer:

{ \bf{ =  \sin(4x)  + 2 \sin(2x) }} \\  = { \bf{2 \sin(2x) \cos(2x)   + 4 \sin(x)  \cos(x) }} \\  { \bf{ = 4 \sin(x) \cos(x) . ({ \cos }^{2}  x -  { \sin}^{2} }x) + 4 \sin(x) \cos(x)  }  \\  = { \bf{4 \sin(x) \cos(x)  ( { \cos }^{2}x -  { \sin }^{2}x + 1)  }} \\  = { \bf{4 \sin(x) \cos(x)  }(2 { \cos }^{2} x)} \\  = { \bf{8 \sin(x)  { \cos}^{3}x }}
