Factor the numerator: (x-2)(x+1) leads us to BELIEVE that x = 2 and x = -1 are zeroes

BUT looking at the denominator x cannot equal 2 (cannot have a value of zero in the denminator)

so the only zero left is at x = -1

Just wanted to let you know that writing service also can manage problem solving type of work just as multiple choice questions.
