Question

factorise 12x^2-7x+1

​

Answer 1

Answer:

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

Step-by-step explanation:

let us write 12x*2-7x+1 as 12x*2-4x-3x+1

because 7x=4x+3x

now from 12x*2-4x from these two terms take 4x common so we can write it as

4x(3x-1) keep this a side

Now, move to the another terms which are (- 3x+1 )

now combine both of them as

4x(3x-1)-(3x-1)=take( 3x-1) as common now that equation can be written as (4x-1)(3x-1)

Answer 2

Answer:

$\sf12 {x}^{2} - 7x + 1 \\ \sf= 12 {x}^{2} - 4x - 3x + 1 \\ \sf= 4x(3x - 1) - 1(3x - 1) \\ \sf = (3x - 1)(4x - 1)$
