@tuition.at.ells: Completing the square made easy! 💯 Completing the square can also be used to find the minimum/maximum point of a curve. The board that I threw is the original way of completing the square. Just a quick fact, completing the square comes from the geometric interpretation of quadratic expressions. Originally, mathematicians visualized as an actual square with area, and the linear term as part of the square’s perimeter. They would then "complete" the square by adding and subtracting the necessary constant term to form a perfect square trinomial. This method was crucial in solving quadratic equations before the quadratic formula was derived.
