Question

Design a class named
QuadraticEquation for a quadratic equation ax²+bx+c = 0. The class
contains:
■ Private data fields a, b, and c that represent three coefficients.
▪ A constructor with 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 getRoot1 () and getRoot2 () for returning two roots
of the equation
r1=
-b+√√√b² - 4ac
2a
and r₂ =
-b-√√b² - 4ac
2a
These methods are useful only if the discriminant is nonnegative. Let these
methods return 0 if the discriminant is negative.
Draw the UML diagram for the class then implement the class. Write a test
program that prompts the user to enter values for a, b, and c and displays the
result based on the discriminant. If the discriminant is positive, display the two
roots. If the discriminant is 0, display the one root. Otherwise, display "The
equation has no roots."

Goal 1: Update the Fractions Class Here we will overload two functions that will used by the Recipe class later: multipliedBy, dividedBy Previously, these functions took a Fraction object as a parameter. Now ADD an implementation that takes an integer as a parameter. The functionality remains the same: Instead of multiplying/dividing the current object with another Fraction, it multiplies/divides with an integer (affecting numerator/denominator of the returned object). For example; a fraction 2/3 when multiplied by 4 becomes 8/3. Similarly, a fraction 2/3 when divided by 4 becomes 1/6. Goal 2: Update the Recipe Class Now add a private member variable of type int to denote the serving size and initialize it to 1. This means all recipes are initially constructed for a single serving. Update the overloaded extraction operator (<<) to include the serving size (sample output below for an example of formatting) . New Member functions to the Recipe Class: 1. Add four member functions…
