(Algebra: quadratic equations) Design a class named QuadraticEquation for a quadratic equation ax² + bx + x = 0. The class contains: ■ Private data fields a, b, and c that represent three coefficients. ■ A constructor for the arguments for a, b, and c. Three getter methods for a, b, and c. ■ A method named getDiscriminant () that returns the discriminant, which is b² - 4ac. ■ The methods named getRootl() and getRoot2() for returning two roots of the equation -b + √b² - 4ac -b-√b² - 4ac 2a "₁ and 12 = 2a These methods are useful only if the discriminant is nonnegative.

Concept of memory addresses in pointers

The concept of pointers in high-level languages was introduced in C programming. Pointers are simply the variables that are used to store memory addresses of another variable. These special variables are generally used in the languages such as C Programming and C++ Programming, where it allows the programmer to work more deeply with memory and its addresses.

(Algebra: quadratic equations) Design a class named QuadraticEquation for
a quadratic equation ax² + bx + x = 0. The class contains:
Private data fields a, b, and c that represent three coefficients.
A constructor for the arguments for a, b, and c.
Three getter methods for a, b, and c.
■ A method named getDiscriminant () that returns the discriminant, which is
b² - 4ac.
■ The methods named getRootl() and getRoot2() for returning two roots of
the equation
-b + √b² - 4ac
2a
-b - √b² - 4ac
2a
and 12
These methods are useful only if the discriminant is nonnegative. Let these meth-
ods return 0 if the discriminant is negative.
