Computer Programming 1 Lab: Selection Control Structures The roots of the quadratic equation ar' + bx + c-o, a # 0 are given by the following formula: 2a In this formula, the term b2-4ac is called the discriminant. If b2 4ac 0, then the equation has a single (repeated) root. If b2 -4ac 0, the equation has two real roots. If b-4ac
