Description
Lab objectives:
- Editing and running a python application using an IDE (IDLE)
- Introducing the steps of designing a solution and testing
- Download and install Python and IDLE on your Machine: https://www.python.org/downloads/
A quadratic equation is can be represented as follows:
y = ax2 + bx + c
Our Quadratic equation solver will find the Reel values of x (roots) that make y = 0.
- Manually fill in the following Table:
- You may use a calculator not a program.
| Expected | Expected | |||
| a | b | c | delta | Roots |
| -1 | 1 | -1 | ||
| 1 | 2 | 1 | ||
| 2 | -10 | 12 | ||
| 0 | 3 | -2 | ||
| 1 | -6 | 9 | ||
| 1 | 4 | 3 | ||
| 3 | 0 | 0 |
- In Idle type, save and run a file containing the exactly the following program:
- Type it yourself. Do not copy and paste.
- List any error and corrections that you made before being able to run the program
- For each of the seven input values run the program. Complete the table below showing, in addition to the expected results already calculated, the observed results.
| Expected | Expected Results | Observed Results | |||
| a | b | c | delta | Roots | |
| -1 | 1 | -1 | |||
| 1 | 2 | 1 | |||
| 2 | -10 | 12 | |||
| 0 | 3 | -2 | |||
| 1 | -6 | 9 | |||
| 1 | 4 | 3 | |||
| 3 | 0 | 0 |
- Analyze by comparing the expected to the observed results and write your observations.
Deliverables:
A Lab report including the following:
- A list of errors that you encountered before being able to run the program.
- The table showing the expected results and the observed results.
- Analysis and observations when comparing the expected and the observed results
- Write your Recommendations to improve the program and do a design (flowchart or pseudocode, not a program), that includes your recommendations.
To Be Submitted on Blackboard before due Date.

Policy on Cheating and Plagiarism:
Plagiarism on assignments and project work is a serious offense. If plagiarism is detected, a student will be subject to penalty, which ranges from receiving a zero on the assignment concerned to an “F” in the course.
