I'll do you one better. Here is how to complete the square on any quadratic:

Step 1: Make sure the equation is in standard form. This one is, so go on.

Step 2: Add the additive inverse of the constant term to both sides.

Step 3: Divide both sides of the equation by the coefficient on

Step 4: Divide the coefficient on the first degree term by 2, square the result, then add that result to both sides of the equation.

Step 5: You will have created a perfect square trinomial in the LHS of the equation. Factor it.

Step 6: Take the square root of both sides remembering to consider both the positive and negative root.

Step 7: Add the additive inverse of the constant term on the left to both sides.

Step 8: Simplify, remembering to remove pairs of factors of the radicand from under the radical.
