Completing the SquareCheatsheet

The whole topic on a page or two, for the night before.

A complete 14-page IGCSE guide to completing the square. It starts with perfect square identities, then teaches the method step by step, first when the coefficient of x² is 1 and then when it isn’t, including negative leading coefficients. Later sections use the completed square form to solve quadratic equations in surd form and decide how many real solutions an equation has. It also derives the quadratic formula. Every method comes with fully worked examples and an expand-to-check step. It ends with a summary, a quick-reference exam strategy and exam tips.
