*3.1 (Algebra: solve quadratic equations) The two roots of a quadratic equation ax2 + bx + c = 0 can be obtained using the following formula:

r1=-b+2b2-4ac and r2=-b-2b2-4ac 2a 2a

b2 - 4ac is called the discriminant of the quadratic equation. If it is positive, the equation has two real roots. If it is zero, the equation has one root. If it is negative, the equation has no real roots.

Write a 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 two roots. If the discriminant is 0, display one root. Otherwise, display The equation has no real roots.

Note that you can use Math.pow(x, 0.5) to compute 2x. Here are some sample runs.

Enter a, b, c: 1.0 3 1

The equation has two roots -0.381966 and -2.61803

 Enter a, b, c: 1 2.0 1 The equation has one root -1 

Enter a, b, c: 1 2 3 The equation has no real roots 

3.1 isn't the section I needed help with. I need help with 3.2, which is based on 3.1

3.2 (Game: add three numbers) The program in Listing 3.1, AdditionQuiz.java, gen- erates two integers and prompts the user to enter the sum of these two integers. Revise the program to generate three single-digit integers and prompt the user to enter the sum of these three integers.
