Write a C++ program regarding the discriminant(b^2-4ac) of the quadratic formula. The program must be able to read in the value of the a,b, and c of the discriminant and perform the following:

. If the value of the discriminant is positive, program should print out that the equation has two real roots and prints the values of the two roots.

. If the discriminant is equal to 0, the roots are real and equal.

if the value of the discriminant is negative, then the equation has two complex roots.

A sample program is below:

Enter values for a, b and c:- 2 10 3 Discriminant = 76

Equation has two real roots Roots are as follows:- x1 = -0.320551 x1 = -0.320551

Any character to end:-

Please write an explanatory comment on every line of code, thank you in advance.
