For quadratic equations that cannot be solved by factorising, we use a method which can solve ALL quadratic equations called completing the square. We use this later when studying circles in plane analytic geometry.Completing the square comes from considering the special formulas that we met in ...
And that’s why we get two solutions when quadratics are involved! 1. Solving by Factorising This is by far the easiest and quickest way to solve a quadratic equation, and if you are not told otherwise, then always spend a minute or so seeing if the equation will factorise. Note: For ...
