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