Just Now We will consider three approaches to solving quadratic equations. The first is a formula which is generally applicable, the second can only be used if the equation can be factorised and the third, completing the square (from which the formula for the solution of a quadratic equation is derived), is also generally applicable but less easy to use than the first.
