    How to Solve a Quadratic Equation by Completing the Square

    1. Put the x-squared and the x terms on one side and the constant on the other side.
    2. Divide both sides by the coefficient of x-squared (unless, of course, it’s 1).
    3. Take half of the coefficient of x, square it, then add that to both sides.
    4. Factor the left side.
