Exercise 6. Write a program to solve the quadratic equation ax2 +br+c = 0 using the standard quadratic formula or the alternative formula. Your program should accept values for the coefficients a, b, and c as commandline input and produce the two roots of the equation as output Your program should detect when the roots are imaginary, but need not use comple:x arithmetic explicitly. You should guard against unnecessary overflow, underflow, and cancellation. When should you use each of the two formulas? Try to make your program robust when given unusual input values. Any root that is within the range of the floating-point system should be computed accurately, even if the other is out of range. Test your program using the following values for the coefficients 6 6 x 10305 x 1030x 1030 10 3.999999 1030 10-30 ame your code quad.C
