The answer would be "D. It will be an isosceles triangle." because no mater where the 3rd going of the triangle lands, it will always have two side of equal length.
I factored the polynomial and its factors turned out to be (x-1)(x^2-2x-4), which eliminated the possibilities of 2 and 3. Then i replaced the (-1) in the place of the x and it turned out to be equal to 2, making the first statement true.
