    To quote my answer to the question I answered (though you asked it first):

    "The first step of completing the square, regardless of the problem, is making sure that the squared term doesn't have a coefficient. Since that's true for this equation, you isolate the constant, or - 3 in this case, which that would be the answer. You'd end up with x^2-x = 3."
