Quadratic

 

 

 

Assignment:

 

1.    Write a program to input the coefficients of a, b, and c for a quadratic equation.  Remember that a quadratic equation can be summarized in the form:

 

             ax²  +  bx  +  c  =  0

 

       The program should compute the two roots for the equation.

 

             x =

 

2.    Your two answers should be printed out to 4 decimal places, + 0.0001.

 

3.    You do not have to error-trap for a negative determinate situation (if b² - 4ac < 0).  All the test inputs will result in real-number answers.

 

 

Instructions:

 

1.    Write your program, test it, and then run these 3 sample inputs:

 

       x² - x - 6 = 0                        x² + x -   =  0                      -2x² + 5x + 17 = 0

 

2.    Here are decimal equivalencies to use for inputs to the middle problem:

 

           =  0.125; -   =  - 0.03125;

 

3.    Turn in your source code and run output.
