Write a program to the quadratic equation. We know that in quadratic formula:

if ax^2 + bx + c = 0,

then x1 = [-b + sqrt(b^2 - 4ac)] / 2a

and x2 = [-b - sqrt(b^2 - 4ac)] / 2a

The program asks the user to enter coefficients a, b, and c, then solve for and display x1 and x2.

Don't forget to check if coefficient a is zero, then x1 = x2 = -(c / b).

Include math.h to use the sqrt() function.

This program is for the c language.
