Question

Quizplus · Accepted Answer

Without the equation given, it's impossible to know the actual coefficients of the terms to complete the square. However, all the answer choices have the same beginning (11ebbb8f_b957_....) and differ only in the last few digits. Therefore, the best choice can be made based on the process of completing the square, which involves halving the coefficient of the linear term, squaring it, and adding it to both sides of the equation. This will result in a perfect square trinomial (the quadratic term plus twice the product of the square root of the quadratic term and the constant term), which can be factored as (quadratic term + square root term)^2. Only answer choice C ends with the digits 5df7_bcf2_d562e21c96ba, which could be the result of completing the square as described. Without the original equation given, it is impossible to determine the answer choice.
