    f(2)=4-6=-2 so f(x)-f(2)=x^2-3x+2=(x-2)(x-1)..... when you divide it with (x-2) you get x-1 so lim of (x-1) as x approaches to 2 is 1

    = (x^2-3x - [(2)^2 - 3(2)])/x-2 =lim x approaches 2 (x^2 - 3x - (-2)/x-2 =lim x approaches 2 (x^2 - 3x +2)/x-2 = (4-3(2)+2)/2-2 = 0/0 =lim x approaches 2 ((x-2)(x-1))/(x-2) =lim x approaches 2 (x-1) = 2-1 = 1 answer solution of my prof ^^
