Question

Quizplus · Accepted Answer

To make the trinomial a perfect square, we need to take half of the coefficient of the middle term and square it. The original expression ends with 4b4ff85e8c93, which tells us the middle term has a coefficient of 8a2d. Half of this coefficient is 4176, and its square is 1745dcd0. Adding this to the original expression gives 11ec1544_3812_8527_8a2d_b186bcf4cd33, which is in choice C.
