Find the roots of quadratic equation, using OOP. Define a class named "QuadraticEquation" Having three double variables a, b, and c that are coefficient of quadratic equation. Have a parameterized constructor. Mutators and accessors for a, b, and c. A function that finds discriminant, and two functions to get two real roots. If discriminant is greater than 0, it has two roots and print them. If discriminant is equal to 0, that has one root, otherwise no real root
