Quadratic Curve – Coordinates of the Turning Point (Part II)

In Part (I), we saw how to work out the coordinates of the turning point on quadratic curve that has solutions – that is the curve crosses the x-axis at one or two points.

But what if the quadratic equation does not have any solutions – meaning the curve is either above or below the x-axis.

In this case, to find the coordinates of the turning point, we use COMPLETING THE SQUARE method.
