Question

**Code Completion Exercise**

**Problem 6:**

Complete the method shown below by filling in the blank such that the method would generate and return the value of the mathematical expression \( b^2 - 4ac \). The method should not print anything to the output. (2 points)

```java
public double calculate(double a, double b, double c) {
double result = ________________________________;
return result;
}
```

**Explanation:**

This code snippet asks you to fill in the calculation for the expression \( b^2 - 4ac \), a common expression in mathematics related to solving quadratic equations. The formula represents the discriminant of a quadratic equation \( ax^2 + bx + c = 0 \).

To complete this, the expression should be `(b * b) - (4 * a * c)` or `Math.pow(b, 2) - (4 * a * c)` depending on how you want to represent squaring \( b \). The result should then be stored in the variable `result`, which is returned by the method.

Instructor note: This lab is part of the assignment for this chapter. HINT: 1). The decision means how many times to flip the coin. 2). Use a random integer variable to indicate the head or tail in each toss. Java Define a method named coinFlip that takes a Random object and returns "Heads" or "Tails" according to a random value 1 or 0. Assume the value 1 represents "Heads" and 0 represents "Tails". Then, write a main program that reads the desired number of coin flips as an input, calls method coinFlip() repeatedly according to the number of coin flips, and outputs the results. Assume the input is a value greater than 0. Ex: If the random object is created with a seed value of 2 and the input is: 3 the output is: Heads Tails Heads Note: For testing purposes, a Random object is created in the main() method using a pseudo-random number generator with a fixed seed value. The program uses a seed value of 2 during development, but when submitted, a different seed value may be used…
