Completing the square is done as follows:<span>
1. Write
the equation in a way that the constants are in the right side while the terms
with x are on the left.
9x2 +54x = 7
2.
Make sure that the coefficient of the x^2 term is 1.
9(x2 + 6x) = 7
<span>3.
Adding a term to both sides that
will complete the square in the left side. This is done by dividing the
coefficient of the x term by 2 and squaring it. Note: The same amount should be
added to the right side to balance the equation.</span>
9(x2 + 6x + 9) = 7 + 81
<span>9(x+3)^2 = 88</span></span>
