Half it,Square,Add it to Both Sides. If you can remember this little
saying you can learn how to use "Complete the Square".

Step 1. Move all of your x's to the same side of the equation and a constant to the other side.

Step 2. Take the B term "Half it, Square it, Add it to Both sides" and add the constant terms together.

Step 3. Rewrite the side with the x's in factored form as a perfect square.

Step 4: Take the square root of each side and then solve for x.
