This has been most apparent to me in A-level physics. In A-level physics the many equations needed are provided on a data sheet. You don’tneedto memorise them. However, in my experience, pupils who know the equations off by heart are significantly better at using them to answer exam ...
These are quadratic simultaneous equations. let the numbers be x and y. x + y = 9 x2 + y2 = 41 From the first equation, y = (9-x) Now substitute this in the second equation. x2 + (9-x)2 = 41 x2 + 81 - 18x + x2 = 41 2x2 - 16x + 81 = 41 2x2 - 16x + 40 ...
