Question

Factorise 12x2 - 7x + 1.​

Answer 1

$\huge\sf\underline\purple{Solution}$

12x²-7x+1

12x²-3x-4x+1

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

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

$\huge\sf\underline\purple{Verification}$

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

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

12x²-4x-3x+1

12x²-7x+1 Hence verified

Answer 2

$\LARGE{ \underline{\underline{\sf{Solution:}}}}$

$12x² - 7x + 1$

$12x² - 3x - 4x + 1$

$3x(4x- 1) -1 (4x-1)$

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