Complete the square and turning points
WebSo, to answer your question, by completing the square we write a quadratic into a form that we can use to determine the minimum point based on the translation that has taken place on it: If f(x) = x², we can translate it with the same function above, so, f(x - a) + b = (x - a)² + b, which you might recognise as the completed square form. WebExample 1: perfect square. Find the closest perfect square by dividing the coefficient of x by 2. The coefficient of x is 8, so when we divide this by 2, we get 4. 2 Expand the perfect square expression. 3 Compare the constant term in the perfect square to the original expression, and adjust as needed.
