Answer:

The answer is ( 3x - 1 ) ( 4x - 1 )

Step-by-step explanation:

The given polynomial is : 12x^{2}  - 7x + 1

To factorize it, we have to find 2 numbers such that their product is 12*1=12 and sum is -7

i.e. to find two numbers p,q such that pq = 12 * 1 = 12 and p + q = -7

Let p,q be 4,3

Here,

12x^{2}  - 7x + 1 \\= 12x^{2}  - 4x - 3x + 1

= 4 x ( 3x - 1 ) - 1 ( 3x - 1 )

This can be simplified and written as ( 3x - 1 ) ( 4x - 1 )

Hence,

12x^{2}  - 7x + 1 =( 3x - 1 ) ( 4x - 1 )
