QUADRATIC EQUATIONS
• Quadratic Formula : If b2 – 4ac ≥ 0, ... Every quadratic equation has at least two roots. (iv) Every quadratic equations has at most two roots. ... if it has, find them by the method of completing the squares. Solution : The discriminant = b2 – 4ac = 49 – 4 × 6 × 2 = 1 > 0 So, the given equation has two distinct real roots.
