Below is a "complete the square problem" from a math help site on the internet.
This is the original problem. 4x2 – 2x – 5 = 0
Move the loose number over to the other side. 4x2 – 2x = 5
Divide through by whatever is multiplied on the squared term.
x^21/2x=5/4. How did 2x suddenly become 1/2? Thanks!!

The instructions want you to "divide (both sides of the equation) by the coefficient of the squared term", which is 4.
2x divided by 4 is = x/2
