Why couldn't I have plugged my results in from the quadratic formula? When I did that I only got one working number.

Using the quadratic formula to test statement 1 should give you two answers. Keep in mind that you have to set the equation equal to zero - so in this case, you'd have n^2 + n - 6 = 0. If you plug that into the quadratic equation, you will get two answers: 2 and -3
