Then use this to tell the user how many solutions the equation has and what kind of solutions there are. Recall that the discriminant D is given by D = b 2- 4 ac. That is, it's the part of the quadratic formula that is under the square root. The value of the discriminant tells how many solutions an equation has as follows: When D &gt; 0, the equation has 2 real solutions When D = 0, the equation has 1 real solution When D &lt; 0, the equation has 2 imaginary solutions Part I: Discriminant Computation (the major task) First collect your inputs and compute the discriminant. Your program should display the general form required for the equation and ask the user to input the coefficients, as demonstrated below. Then compute the discriminant, store it in a variable, and display it. coefficients, as demonstrated below....
