At first glance, you might be led to believe that this limit does not exist, since the denominator is equal to 0 when x=1, But then you will notice that the numerator is also equal to 0 when x=1. In this case, since we are dealing with polynomials, we can find a factor (x-1) in the numerator. Indeed, we have x2 - 3x +2 = (x-1)(x-2). So, for ,
which implies
