Solution of a Quadratic Equation by Completing the Square       Following steps are involved in solving a quadratic equation by quadratic formula         ·    Consider the equation , where a ¹ 0         ·    Dividing throughout by ‘a’, we get                      ·    Add and subtract , we get             ,                      ·    If taking square root of both sides, we obtain             …

Solution of a Quadratic Equation by Factorisation       Consider the following products.              Above example illustrate that whenever the product is 0, at least one of the factors is 0. Imp: If a and b are numbers, then ab = 0, iff a = 0 or b = 0.     Above principle is used in solving…
