The first few steps in solving the quadratic equation 9x2 + 49x = 22 − 5x by completing the square are shown.9x2 + 49x = 22 − 5x9x2 + 54x = 229(x2 + 6x) = 22which is the best step to do next to solve the equation by completing the square? a. 9(x2 + 6x + 3) = 25b. 9(x2 + 6x + 3) = 49c. 9(x2 + 6x + 9) = 31d. 9(x2 + 6x + 9) = 103

The next step is to add the square of half the x-coefficient inside parentheses and the equivalent amount to the other side of the equation.

9(x² + 6x + (6/2)²) = 22 + 9(6/2)²

9(x² + 6x + 9) = 103 . . . . . matches selection D.
