Question

Factorise :
12x2-7x+1

Answer 1

Step-by-step explanation:

Hello friend

______________________________________________________

12x² - 7x + 1

 

= we can find two numbers such that pq = 12 x 1 = 12 and p + q = -7

= Here, 12x² - 7x + 1 = 12x² - 4x - 3x + 1

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

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

Hope it will help u

Answer 2

12x2-7x+1

= 12x^2 - 4x-3x +1

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

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

= x = 1/4 or not x =1/3
