Completing the square

KS4, KS5. This takes the student through the steps to completing the square for 'ax-squared' where a = 1 initially. It uses these results to establish the minimum point of the curve and to sketch the curve. It finally illustrates how to transform the basic graph y = x-squared to the given quadratic. It is encouraged to try these transformations on previous exercises.
