Solve for x by completing the square:
Complete the square in x by adding the square of half the x-coefficient to both sides, this is:
Now factor the left side.
Now take the square root of both sides. You'll get two answers.
or Now subtract 3 from both sides in each of these.
or ...and these are the two roots.

Follow this procedure to solve a quadratic by completing the square:
:
Step 1: Put the equation in the form . In this case you don't have to do anything because it is already in the proper form.
:
Step 2: Find divide the coefficient on the 'x' term by 2: 6/2 = 3
:
Step 3: Square this result: 3 * 3 = 9
:
Step 4: Add this result to both sides of the original equation
:
Step 5: Factor the left side of the equation. This should be easy because you added the 9 to make the left side a perfect square.
:
Step 6: Take the square root of both sides and then add -3 to both sides. Don't forget that you need to consider both the positive and negative square roots.
