Method for completing the square

WebCompleting the square is a way to write any quadratic x 2 +ax+b as x 2 +p, which allows us to solve the quadratic equation.. You can do a similar thing by writing any cubic x 3 +ax 2 +bx+c as a "depressed cubic" of the form x 3 +px+q. This allows us, through more complicated methods, to solve the cubic equation. WebCompleting the Square One method is known as completing the square. Using this process, we add or subtract terms to both sides of the equation until we have a perfect square trinomial on one side of the equal sign. We then apply the square root property. To complete the square, the leading coefficient, a a , must equal 1.
