Best ResponseYou've already chosen the best response.1When you have a quadratic with 1 as the coefficient of the x^2 term, to complete the square, take half of the xterm coefficient, and square it.

Best ResponseYou've already chosen the best response.1No. The complete the square term is always positive. Half of 4 is 2 2 squared is 4. The answer is 4.

Best ResponseYou've already chosen the best response.16 is incorrect. The complete the square term has to be a perfect square. 6 is not a perfect square, so 6 cannot possibly be correct.
