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^2-1/2x=5/4. How did -2x suddenly become -1/2? Thanks!!
