... Memorising this formula offers the speediest way to solve quadratics. (But if speed isn’t your primary concern, then the box method we’ve described, that is, completing the square, will never let you down and will keep you close in touch with your understanding of why solving quadratics works the wa ...

... Basis, span and dimension: As I argued previously, the kernel of D2 consists of all functions of the form c0+c1t where c0 and c1 are constants. Thus, the kernel of D2 consists of linear combinations of the two functions, 1 and t. These are then said to ‘span’ the kernel of D2 and as they are line ...
