Completing the square is a useful technique for solving quadratic equations. It is a more powerful technique than factorisation because it can be applied to equations that do not factorise. ax2 + bx + c is written in the form (Ax + B)2. x2 + bx + as (x + B)2 +. If we expand (x + B) + we get x2 + 2Bx + B2 + C. 2.
