Chapter 4.4, Problem 28SCP
Explanation of Solution
Modifying quadratic method:
- The quadratic method would fail if the coefficient a is 0.
- Invalid values are when a = 0 which is because it makes the denominator of the equation as 0 or if the determinant that is b2 – 4ac is negative because it has no real square root.
- The modified quadratic method is
// Throws an exception if a, b, c are invalid
public static void quad...

Task 03: Read the concept of Binomial coefficient given in chapter-6. Write a method that
takes two parameters n and k and returns the value of Binomial Coefficient C(n, k).
For example, your function should return 20 for n = 6 and k = 3, and it should return 35 for n= 7 and k
= 4. ( confirm it through the Pascal's triangle as given below).

We discussed and did an example of the Quadratic formula in class. Here is the code for the method that I used in that example below. Implement this method in your program. (I suggest your base your Quadratic method on my example from Chapter 8). Modify my method to return 0 for both results and set blnValidEquation to false if the entered values do not have a solution. HINT: If the expression in the square root evaluates to a negative number, there is no valid solution. I gave some pretty strong hints to this one during the lecture.
class Program{static void Main(string[] args){double dblA, dblB, dblC;double dblR1, dblR2;Console.WriteLine("Equation format: ax^2 + bx + c = 0");Console.Write("Enter value for a: ");dblA = double.Parse(Console.ReadLine());Console.Write("Enter value for b: ");dblB = double.Parse(Console.ReadLine());Console.Write("Enter value for c: ");dblC = double.Parse(Console.ReadLine());//Quadratic(dblA, dblB, dblC, out dblR1, out dblR2);if (Quadratic(dblA, dblB,…
You have a card on which the letter J is written on one side and K on the other. You want to seeall of the possible ways the card will land if you drop it n times. Write a recursive method thatprints each session of dropping the cards with J's and K's. For example if you drop it 4 times in agiven session, all possible ways to drop it are as follows (in exactly the specified order):
