Design a class named QuadraticEquation for a quadratic equation ax^2+bx+x=0. The class contains: **private data fields a, b, and

c that represents three coefficients. **a constructor for the arguments for a, b, and c. **three get methods for a, b, and c. **a method named getDiscriminant() that returns the discriminant, which is b2-4ac **the methods named getRoot1() and getRoot2() for returning two roots of the equation, or returning 0 if the discriminant is negative.[/color]
