B) 25
C) -5
D) 0

Question

Quizplus · Accepted Answer

To complete the square, we need to add a number that makes the left side a perfect square trinomial. The formula for completing the square is $\left(\frac{b}{2}\right)^2$, where $b$ is the coefficient of the linear term. Here, $b = -10$, so $\left(\frac{-10}{2}\right)^2 = 25$.
