The IGCSE papers like to throw in standard form questions that require some algebraic manipulation. If you don't do IGCSE you can use this as an extension ...
Converting a quadratic equation from vertex form to standard form is a fundamental skill in algebra. The vertex form of a quadratic equation is given by y=a(x−h)2+ky = a(x - h)^2 + ky=a(x−h)2+k, where ...
