The quadratic formula is used to solve any quadratic equation. the quadratic equation has the form: a*x*x + b*x + c = 0. write a program that will solve a quadratic equation, given the values of a, b and c, and return the larger of the two roots. be sure to handle the appropriate exceptions (the value of a cannot be zero, and you cannot find the square root of a negative number).
