your answer is
12x^2-7x+1
12x^2-4x-3x+1
4x(3x-1)+1(3x-1)
(3x-1)+(4x+1)
answer is 3x-1(and)4x+1
ur ans is correct

Step by step Factorisation :
12x² - 7x + 1
= 12x² - 4x - 3x +1
= 4x(3x - 1) -1(3x +1)
= (4x - 1)(3x +1)
Factorized
Now if we are given to find the zeroes of the above polynomial :
4x -1 =0 and 3x +1= 0
→4x = 1 , → 3x = -1
→x = 1/4 , →x = -1/3
Therefore , x =1/4 or x = -1/3
hi mate
