Question

factorise it..
$3 {x}^{2} y - 3xy + 12x - 12 \\ the \: answer \: should \: come \: as \: 3(x - 1)(xy + 4)$
​

Answer 1

$3 {x}^{2} y - 3xy + 12x - 12$

$3xy(x - 1) + 12(x - 1)$

$(x - 1)(3xy + 12)$

Answer 2

3 {x}^{2} y - 3xy + 12x - 123x

2

y−3xy+12x−12

3xy(x - 1) + 12(x - 1)3xy(x−1)+12(x−1)

(x - 1)(3xy + 12)(x−1)(3xy+12)
