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