    there is an x^2 term and an x term what number do you see right before the x (or what number is right before the x when you don't see a number)?

    x does not equal one but there is 1x in the problem so you are correct to it is 1. So.. to complete the square you always take 1/2 of that number ... so half of 1 is 1/2 Then you square that number 1/2 * 1/2 = 1/4
