If \((x + 1)(x + 2) = 0\), then \(x + 1 = 0\) or \(x + 2 = 0\), or both. Factorising quadratics will also be used to solve the equation. The product of \(x + 1\) and ...

Here are some examples of quadratic equations in this form: \(2x^2 - 2x - 3 = 0\). \(a = 2\), \(b = -2\) and \(c = -3\) \(2x(x + 3) = 0\). \(a = 2\), \(b = 6\) and ...
