Answer:

12x(x+1)(x-1)

Step-by-step explanation:

12 {x}^{3}  - 12x \:  =  12 \times x \times x \times x - 12 \times x  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:    \:   = 12 \times x \times (x \times x - 1) \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \:  = 12x( {x}^{2}  - 1) \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   = 12x(x  + 1)(x - 1) \\ {by using \: the \: identity \:  {a}^{2}  -  {b}^{2}  = (a + b)(a - b)}
