Answer:

 \boxed{\sf (3x - 1)(4x - 1)}

Step-by-step explanation:

 \sf Factorize: \\  \sf \implies  12{x}^{2}  - 7x + 1 \\  \\ \sf \implies  12{x}^{2}  - (3 + 4)x + 1  \\  \\ \sf \implies  12{x}^{2}  - 3x - 4x + 1 \\  \\ \sf \implies 3x(4x  - 1) - 1(4x - 1) \\  \\ \sf \implies (3x - 1)(4x - 1)

Additional:

 \sf (3x - 1)(4x - 1) = 0 \: split \:  into \\ \sf  two \:  equations \: to \: get \: x: \\  \sf \implies (3x - 1) = 0 \:  \:  \:  \: or \:  \:  \:  \: (4x - 1) = 0 \\   \\  \sf  \implies 3x = 1 \:  \:  \:  \: or \:  \:  \:  \: 4x = 1 \\ \\   \sf  \implies x =  \frac{1}{3}  \:  \:  \:  \: or \:  \:  \:  \: x =  \frac{1}{4}
