For example, look at the following roots: If x = -1/2, ( x - (-1/2)) is your factor, which you write as ( x + 1/2). The reason is that all of the exponents are whole numbers for the variable x (2 in the first term, 1 in the second term, and 0 in the third term). So if $ 2 \ + \ \sqrt{ 3 } $ is one root then $ 2 \ \ \sqrt{ 3 } $ must be the other root. You multiply both the numerator & denominator by sqrt(2) and get. And so that's the contradiction.
