Solve by completing the square. x 2 +12x = 5

X = −6 + √41 or −6 − √41

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

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