Answer» (4A 2b 3c)2 = 16a2+ 4b2 + 9c2+16ab + 12BC - 24ca. Step-by-step explanation:(4a - 2b - 3c)2= (4a)2 + (-2b)2+ (-3c)2 + (2 x 4a x (-2b)) + (2 (-2b) (-3c)) + (2 x (-3c) x( 4a) ((a+b+c)2 = a² + b° + c² + 2AB + 2bc + 2ca)) 16a2 + 4b2 + 9c2 - 16ab + 12bc - 24ca HENCE, (4a 2b 3c)2 = 16a2+ 4b2 + 9c2+16ab + 12bc - 24ca.
