Given the equation  $x^2+18x=0$  how do you find the number to add to both sides to help you complete the square?  

• Divide 18 by 2, then square that number and add it to both sides of the equation

• Square 18 and then add it both sides of the equation

• It already is a perfect square

• Subtract 18x from both sides and then divide both sides by x to find the answer
