    Given the polynomial equation x^3 - 6x = 3x^2 - 8. Which can be simplified into (x^3) - 3 (x^2) - 6x + 8 = 0. The roots of the given equation are x = - 2, x = 1 and x = 4. The order of equation also represents the number of roots of the equation given. Since the highest exponent is 3, there also 3 roots. So the answer is D. 2 - 2, 1, 4
