Problem 2: Solving a quadratic equation 1) Write a program in C++ that takes integer coefficients a, b, c from the user and displays the following quadratics equation ax2+bx+c=0 D=b2-4ac a) D =0; the equation has a double solution. 2) Modify the code to calculate the discriminant D using the following formula 3) For a non-zero coefficient a, discuss the roots of the quadratic equation: D>0; the equation has two different solutions X1 and X2. X1 = (-b-sqrt (D))/2a X2 = (-b+sqrt (D))/2a b) c) If D
