How to solve quadratic equations by completing the square. Here we have all examples including leading coefficients. With and without fractions. Creating a perfect square trinomial on the left side of a quadratic equation, with a constant (number) on the right, is the basis of a method called completing the  Task. Enrico has discovered a geometric technique for ''completing the square'' to find the solutions of quadratic equations. To solve the equation x^2 + 6x + 4  the many ways you can solve a quadratic equation is by completing the square . In this method, you want to turn one side of the equation into a perfect square  We can use a technique called completing the square to rewrite such an equation so that we can quickly identify the circle's center point (h,k) and the radius.

A turning point can be found by re-writting the equation into completed square form. When the function has been re-written in the form `y = r(x + s)^2 + t`, the minimum value is achieved when `x = -s`, and the value of `y` will be equal to `t`. Completing the square applies to even the trickiest quadratic equations, which you’ll see as we work through the example below. Your Step-By-Step Guide for How to Complete the Square. Now that we’ve determined that our formula can only be solved by completing the square, let’s look at our example formula again: complete the square x^2-4x+7. complete the square (x^2-2x.
