Question

factorise 12xpawer 2 -7x+1​

Answer 1

Answer:

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

Step-by-step explanation:

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

Answer 2

Answer:

$12 {x}^{2} - 7x + 1 \\ \\ = 12 {x}^{2} - (4 + 3)x + 1 \\ \\ = 12 {x}^{2} - 4x - 3x + 1 \\ \\ = 4x(3x - 1) - 1(3x - 1) \\ \\ = (4x - 1)(3x - 1) \\ \\ either \: 4x - 1 = 0 \\ \\ = > 4x = 1 \\ \\ = > x = \frac{1}{4} \\ \\ or \: 3x - 1 = 0 \\ \\ = > 3x = 1 \\ \\ = > x = \frac{1}{3}$

hope it helps uH :)
