WebFactorising is the reverse of expanding brackets, so it is, for example, putting 2x² + x - 3 into the form (2x + 3) (x - 1). This is an important way of solving quadratic equations. The first step of factorising an expression is to 'take out' any common factors which the terms have. So if you were asked to factorise x² + x, since x goes into ... WebWe can solve quadratics through factorising by following these 4 easy steps. Example: Solve the quadratic equation, \textcolor {blue} { x^2-3x+2=0} by factorisation. Step 1: …
