Design a class named QuadraticEquation for a quadratic equation

. The class contains:


• Data fields a, b, and c that represents three coefficients.


• A constructor for the arguments for a, b, and c.


• Three get functions for a, b, and c.


• A function named getDiscriminant() that returns the discriminant, which is





• The functions named getRoot1() and getRoot2() for returning two roots of the equation








These functions are useful only if the discriminant is non-negative. Let these functions return 0 if the discriminant is negative.
