Problem 2510. Solving Quadratic Equations (Version 1)
Quadratic equations have the form: ax^2 + bx + c = 0. Example: x^2 + 3x + 2 = 0, where a = 1, b = 3, and c = 2. The equation has 2 real solutions (roots): x = -1 and x = -2. The quadratic formula can be used to find the roots:

The formula can be translated into the computation of two roots x1 and x2:
x1 = -b + ... x2 = -b - ...
Complete the function to solve the quadratic equation denoted by a, b, and c. Assume the discriminant --- b^2 - 4ac --- is not negative, ensuring that x1 and x2 are real.
