Task 2: (1) (ii) The roots of the quadratic equation ax + bx + c = 0 are given by X= -b b-4ac 2a . Based on the sign of the discriminant D (i.e. D=b-4ac), it is possible to discern the nature of the roots according to: D > 0: A pair of non-equal real valued roots. D = 0: A pair of equal real valued roots. D
