Question

4. Factorise :
(i) 12.x2 - 7x + 1​

Answer 1

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

I hope this helps.

Answer 2

Answer:

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

hope it helps uH ✔
