deepak349789: in the second column how it came -2

champion360: by middle term splitting

deepak349789: we can't directly apply middle splitting term while doing division

champion360: no it can be applied bro

champion360: it is easier also

deepak349789: as bcoz there's -3 and we r subtracting -× from it and keeping the + sign...this made me confuse

deepak349789: sorry -3x-x(+)??? this make confusion

champion360: IF YOU ARE SATISFIED BY MY ANSWER PLEASE MARK ME BRAINLIEST

kalpjain: see friend when x square is divided by x answer will be x in first column. when we multiply x and -1, then -x will come. sign will change and -3x+x=-2x. then -2x divided by x will be -2

Answered by champion360

${x}^{2} - 3x + 2 \\ = {x}^{2} - 1x - 2x + 2 \\ = x(x - 1) - 2(x - 1) \\ = (x - 1)(x - 2)$
$so \: when \: (x - 1)(x - 2) \div (x - 1) \\ = (x - 2)$
so answer is (x-2)
